Moonstone is a feldspar gemstone best known for its soft, floating glow called adularescence. As the gemstone moves, this luminous sheen appears to glide beneath its surface, giving moonstone the mysterious appearance that has inspired its name and centuries of folklore.
Although fine moonstone is often associated with a colorless or nearly colorless body and a vivid blue sheen, moonstone can also occur in white, gray, peach, green, brown, and other body colors. Its unusual optical effect, symbolism, and versatility have made it popular in rings, earrings, necklaces, pendants, and other gemstone jewelry.
In this guide, you will learn what moonstone is, why it glows, how moonstone quality is evaluated, how rainbow moonstone differs from traditional moonstone, where the gemstone comes from, what it symbolizes, how durable it is, how to buy moonstone jewelry, and how to care for it properly.
What Is Moonstone?
Moonstone is a gemstone from the feldspar mineral group. Traditional moonstone is associated primarily with intergrowths of feldspar minerals that create microscopic internal layers. When light enters the stone and interacts with these layers, it produces the floating optical effect known as adularescence.
The name “moonstone” comes from the gemstone's moon-like glow rather than from any actual connection with the Moon. Historically, different cultures associated the gemstone with moonlight, love, protection, intuition, renewal, and good fortune.
Moonstone can range from translucent to transparent. Its body color may be colorless, white, gray, peach, green, brown, or other subtle shades, while its sheen may appear white, silvery, or blue depending on the material and viewing angle.
Why Does Moonstone Glow? Understanding Adularescence
Moonstone's signature glow is called adularescence. It occurs when light enters the gemstone and interacts with microscopic layers within its feldspar structure.
Rather than reflecting light only from the surface, moonstone appears to produce a soft glow from within. As the stone is turned, the luminous area seems to move across or beneath the surface.
This mobile sheen is one of the most important characteristics used when evaluating moonstone quality.
What Does Good Adularescence Look Like?
In high-quality moonstone, the sheen should ideally be:
- clearly visible;
- well centered when the stone is viewed face-up;
- mobile as the gemstone is tilted;
- visible across a reasonably broad range of viewing angles;
- strong enough to stand out against the gemstone's body color.
A vivid blue sheen over a nearly colorless and transparent body is particularly prized in fine traditional moonstone, although attractive moonstones occur in many colors and qualities.
What Colors Does Moonstone Come In?
Moonstone is often pictured as a milky white gemstone, but it occurs in a broader range of body colors.
Common moonstone colors include:
- Colorless
- White
- Gray
- Peach
- Green
- Brown
- Yellowish or warm-toned varieties
The visible sheen can also vary. Some stones display a white or silvery glow, while finer material may show a striking blue sheen.
A colorless or nearly colorless moonstone with high transparency and vivid blue adularescence is traditionally considered especially desirable. However, peach, gray, green, and other moonstones can also make beautiful jewelry and may be preferred for their distinctive appearance rather than rarity alone.
Is Rainbow Moonstone Really Moonstone?
Rainbow moonstone is not technically the same mineral variety as traditional moonstone. The material widely sold in the jewelry trade as rainbow moonstone is generally transparent or translucent labradorite, another member of the feldspar family.
Rainbow moonstone can display blue, green, yellow, and sometimes multicolored flashes, which gives it a moonstone-like appearance. Because of this similarity, the trade name “rainbow moonstone” has become widely established.

When shopping online, check the gemstone description so you understand whether the piece contains traditional moonstone or material sold as rainbow moonstone.
Moonstone vs Opalite: What Is the Difference?
Moonstone and opalite can look similar in photographs because both may have a soft, glowing appearance. However, they are very different materials.
|
Names such as “opalite moonstone” can create confusion. When buying jewelry online, rely on the material disclosure rather than appearance or marketing terminology alone.
Where Is Moonstone Found?
Moonstone has been sourced from several locations around the world. Important historical and commercial sources have included:
- Sri Lanka
- India
- Myanmar
- Madagascar
- Tanzania
- Australia
- Brazil
- The United States
- Other feldspar-producing regions
Sri Lanka is especially well known for producing fine traditional moonstone, including material with a relatively colorless body and attractive blue sheen. India has also produced moonstone in a variety of body colors.
Origin alone does not determine quality. When judging an individual moonstone, its adularescence, body color, transparency, inclusions, cut, and overall visual appearance are generally more useful than geographic origin by itself.
How Is Moonstone Quality Evaluated?
Moonstone does not use a universally standardized grading system comparable with diamond grading. Instead, several visual factors are considered together.
The most important are:
- strength and color of adularescence;
- body color;
- transparency and clarity;
- cut and orientation;
- size and overall appearance.
Adularescence
Body Color
Clarity and Transparency
Cut
- cabochons;
- beads;
- carved gemstones;
- rose cuts;
- faceted stones, particularly when the material is sufficiently transparent.
Carat Weight and Size
Adularescence is one of the most important characteristics of moonstone. A strong, attractive sheen that appears centered and moves smoothly across the gemstone generally makes the stone more visually desirable.
The quality of the optical effect should be judged from multiple angles because a moonstone that looks attractive from one position may show a weaker sheen from another.
Traditional fine-quality moonstone is often valued for a nearly colorless body combined with vivid blue sheen. However, moonstone also occurs naturally in peach, gray, green, white, brown, and other subtle shades.
For jewelry, personal preference matters. Someone may prefer the warm tone of peach moonstone or the moody appearance of gray moonstone even if another variety commands a higher market value.
Higher transparency and fewer distracting inclusions are generally desirable in fine moonstone because inclusions can interfere with the visibility and movement of adularescence.
Moonstone may contain characteristic stress fractures sometimes described as “centipede” inclusions because of their appearance.
A few inclusions do not automatically make a gemstone unattractive. Consider whether they significantly reduce transparency, weaken the sheen, or create durability concerns.
The cabochon is the classic moonstone cut. Its smooth, rounded surface usually displays adularescence particularly well.
The cutter must orient the stone carefully so the strongest sheen appears in an attractive position when the gemstone is viewed face-up.
Moonstone can also be found as:
Cut quality should therefore be judged not only by symmetry but also by how well the cut displays the gemstone's optical effect.
Moonstone occurs in a broad range of sizes. Fine-quality material with strong adularescence, attractive transparency, and few distracting inclusions generally becomes more difficult to find in larger sizes.
When comparing moonstone jewelry online, consider both carat weight and millimeter dimensions where available, because two gemstones with similar weight can appear different in face-up size depending on their shape and depth.
What Makes Moonstone Valuable?
Moonstone value is influenced by a combination of characteristics rather than by size alone.
Factors that can contribute to value include:
- strong blue or attractive adularescence;
- high transparency;
- a clean or attractive body color;
- minimal distracting inclusions;
- well-centered sheen;
- good cutting and orientation;
- larger size combined with fine quality;
- quality of the jewelry setting and craftsmanship.
A larger moonstone with weak sheen and heavy inclusions is not automatically more desirable than a smaller stone with vivid, centered adularescence.
Is Moonstone a June Birthstone?
Yes. Moonstone is traditionally recognized as one of the birthstones for June.
This makes moonstone jewelry a meaningful option for June birthday gifts as well as for buyers who simply appreciate the gemstone's soft glow and symbolism.
History and Symbolism of Moonstone
Moonstone has inspired mythology and symbolism for centuries because its floating light resembles moonlight moving across water or clouds.
Historical and cultural traditions have associated moonstone with themes such as:
- love;
- renewal;
- intuition;
- protection;
- travel;
- feminine symbolism;
- good fortune;
- the cycles of the Moon.
Ancient Roman traditions connected the gemstone with lunar imagery, while traditions in India have also regarded moonstone as meaningful in connection with love and relationships.
Such associations are part of moonstone's cultural history and symbolism rather than scientifically measurable properties of the mineral.
What Is the Spiritual Meaning of Moonstone?
In modern crystal and spiritual traditions, moonstone is commonly associated with intuition, emotional balance, renewal, feminine energy, and spiritual reflection.
Some practitioners also connect moonstone with meditation and lunar rituals.
It is important to distinguish these traditions from established science. Claims that moonstone can medically treat stress, hormonal conditions, menstrual symptoms, pregnancy-related problems, insomnia, or other health conditions are not established medical effects. Gemstone jewelry should not be used as a substitute for professional medical care.
Moonstone and Chakra Traditions
In chakra-based spiritual practices, moonstone is sometimes associated with the Third Eye Chakra and Crown Chakra.
Third Eye Chakra
Within these traditions, the Third Eye Chakra is associated with intuition, insight, and inner awareness. Moonstone may be used symbolically during meditation or spiritual practices focused on these themes.
Crown Chakra
The Crown Chakra is traditionally associated with spiritual connection and higher awareness. Some practitioners use moonstone as a symbolic gemstone in practices associated with this chakra.
Chakras and gemstone-energy associations belong to spiritual and metaphysical traditions and are not scientifically demonstrated physiological systems.
How Hard Is Moonstone?
Moonstone has a hardness of approximately 6 to 6.5 on the Mohs scale.
However, hardness measures resistance to scratching, not overall resistance to breaking.
Moonstone also has cleavage and relatively limited toughness compared with more durable gemstones. A hard impact can cause the stone to chip, crack, or break.
For that reason, moonstone jewelry should be worn more carefully than jewelry containing harder and tougher gemstones.
Can Moonstone Be Worn Every Day?
Moonstone can be worn regularly, but the amount of care required depends on the type of jewelry.
Moonstone Earrings
Earrings generally receive fewer hard impacts than rings, making them a practical way to wear moonstone frequently.
Browse our Earrings if you are comparing different gemstone earring styles.
Moonstone Necklaces and Pendants
Pendants and necklaces are also relatively protected during ordinary wear, although the gemstone should still be kept away from hard knocks and abrasive surfaces.
Explore different styles in our Necklaces collection.
Moonstone Rings
Rings experience more direct contact with desks, doors, gym equipment, countertops, and other hard surfaces. Moonstone rings therefore require greater care.
A protective setting such as a bezel or another design that shields vulnerable edges can be a sensible choice for frequent wear.
Explore Moonstone Rings to compare different designs and settings.
Can Moonstone Be Used in an Engagement Ring?
Yes, moonstone can be used in an engagement ring, particularly for someone who values its unusual glow and is willing to treat the gemstone carefully.
However, moonstone is not as durable as diamond, sapphire, or some other commonly used engagement-ring gemstones. Its Mohs hardness of 6 to 6.5 and its cleavage mean it can be more vulnerable to scratches, chips, and impact damage.
If you are considering a moonstone engagement ring:
- choose a protective setting;
- avoid very exposed designs if the ring will be worn daily;
- remove the ring for sports, gym workouts, gardening, and heavy manual work;
- store it separately from harder gemstones;
- have the setting inspected periodically.
If durability is a major priority for daily wear, compare moonstone with harder gemstone options before deciding.
You can also explore different styles within our Engagement Rings collection.
How to Buy Moonstone Jewelry
When buying moonstone jewelry, do not judge the stone from body color alone. The quality and visibility of its adularescence can be just as important.
Use the following checklist when comparing pieces.
Check the Adularescence
Look for a strong sheen that moves as the gemstone turns. Ideally, it should be visible when the stone is viewed face-up and should not disappear after only a tiny change in viewing angle.
Check the Body Color
Colorless material with blue sheen is traditionally prized, but peach, gray, green, and other varieties can also be attractive choices.
Select a body color based on the appearance you prefer rather than assuming one color is automatically suitable for everyone.
Check Transparency and Inclusions
Look closely for heavy cloudiness, obvious fractures, or inclusions that interfere with the optical effect.
Some inclusions are natural and acceptable, but the finest transparent moonstones typically show fewer distracting internal features.
Check the Cut and Orientation
The cut should display the adularescence effectively. In a cabochon, the sheen should ideally appear centered and move smoothly across the dome.
Check the Setting
Because moonstone can chip or cleave when struck, the setting is especially important in rings.
Consider:
- bezel settings;
- halo designs that provide additional surrounding protection;
- lower-profile settings;
- settings that protect the gemstone's edges.
Check Metal Quality
Read the product specifications and confirm the type and purity of the metal used in the jewelry.
Moonstone can pair attractively with white, yellow, or rose-colored metals depending on the body color of the gemstone and the style you prefer.
Confirm the Gemstone Description
Make sure you understand whether the product contains:
- traditional moonstone;
- rainbow moonstone;
- another feldspar variety;
- or a moonstone imitation such as opalite.
A transparent product description is more useful than relying only on a photograph or marketing name.
How to Evaluate Moonstone Jewelry When Shopping Online
Moonstone can be particularly difficult to judge from a single photograph because its adularescence changes with the viewing angle.
When possible, look for:
- multiple photographs from different angles;
- close-up images of the gemstone;
- video showing the moonstone while it moves;
- neutral or realistic lighting;
- gemstone dimensions;
- carat weight where applicable;
- setting and metal details;
- clear gemstone identification;
- return and exchange information.
A video can be particularly helpful because it shows how the sheen travels across the gemstone instead of capturing only one favorable angle.
Red Flags When Buying Moonstone Online
Be cautious if a product listing:
- does not identify the gemstone clearly;
- uses “moonstone” and “opalite” interchangeably;
- does not distinguish rainbow moonstone from traditional moonstone where relevant;
- provides only one heavily edited image;
- makes exaggerated claims about guaranteed healing or medical effects;
- does not identify the metal;
- does not explain returns or exchanges;
- provides no useful size or gemstone information.
If important information is missing, contact the jeweler before purchasing.
How to Clean and Care for Moonstone Jewelry
Moonstone requires gentle care because sudden temperature changes and hard impacts can damage the gemstone.
Cleaning Moonstone
Use warm water, mild soap, and a soft cloth or very soft brush.
- Prepare a small bowl of warm—not extremely hot—soapy water.
- Clean the jewelry gently with a soft cloth or brush.
- Rinse carefully with clean water.
- Dry thoroughly using a soft, lint-free cloth.
Avoid Ultrasonic and Steam Cleaners
Ultrasonic and steam cleaners are not recommended for moonstone because the gemstone can be vulnerable to internal stress, cleavage, heat, and sudden temperature changes.
Avoid Harsh Chemicals
Keep moonstone away from strong household chemicals, harsh detergents, and other substances that may affect the jewelry or its setting.
Protect It From Impact
Remove moonstone rings before:
- gym workouts;
- sports;
- gardening;
- household repairs;
- heavy cleaning;
- other activities where the jewelry may be struck.
Store Moonstone Separately
Store moonstone in a soft pouch or lined jewelry compartment away from harder gemstones such as diamonds, sapphires, and rubies that may scratch it.
Can Moonstone Go in Water?
Brief contact with warm water during normal cleaning is generally appropriate for moonstone. There is usually no need to soak the gemstone for long periods.
Avoid very hot water, sudden temperature changes, steam, or unnecessary prolonged exposure—particularly when the moonstone is part of finished jewelry that may include other gemstones, adhesives, or delicate settings.
Can You “Charge” Moonstone?
In crystal and spiritual traditions, some people place moonstone in moonlight as a symbolic practice known as “charging.” A full moon is especially popular in these traditions because of moonstone's historical association with lunar symbolism.
This is a spiritual practice rather than a scientifically demonstrated change in the gemstone.
If you choose to follow such a ritual, keep valuable jewelry secure and avoid leaving it unattended outdoors where it could be lost, exposed to weather, or damaged.
Does Moonstone Have Healing Properties?
Moonstone is associated in various cultural, spiritual, and crystal traditions with ideas such as calmness, intuition, emotional balance, renewal, and feminine energy.
However, these associations should not be presented as scientifically established medical benefits. There is no reliable basis for claiming that moonstone can diagnose, prevent, or cure conditions such as stress disorders, insomnia, menstrual problems, pregnancy complications, or other health conditions.
Enjoy moonstone for its beauty, history, symbolism, or personal meaning, but seek qualified medical advice for health-related concerns.

Frequently Asked Questions About Moonstone
What is moonstone?
Moonstone is a feldspar gemstone known for adularescence, a floating internal glow that appears to move across the stone as it is viewed from different angles.
Why does moonstone glow?
Moonstone glows because light interacts with microscopic internal layers in its feldspar structure. This optical effect is called adularescence.
What is adularescence?
Adularescence is the soft, mobile light effect seen in moonstone. It appears to float beneath the gemstone's surface and moves as the stone or viewing angle changes.
Is rainbow moonstone real moonstone?
Rainbow moonstone is a widely used trade name, but the material is generally transparent labradorite, another feldspar mineral, rather than traditional orthoclase moonstone.
Is moonstone the same as opalite?
No. Moonstone is a natural feldspar gemstone, while commercial opalite is usually man-made glass. Their glowing appearance can look similar in photographs, so accurate material disclosure is important.
What color moonstone is most valuable?

How should moonstone be cleaned?
Clean moonstone gently with warm water, mild soap, and a soft cloth or brush. Avoid steam cleaning, ultrasonic cleaning, harsh chemicals, extreme heat, and sudden temperature changes.
Does moonstone have healing powers?
Moonstone has traditional and spiritual associations with calmness, intuition, renewal, and emotional balance, but these are cultural or metaphysical beliefs rather than scientifically established medical effects.
Final Thoughts
Moonstone is distinctive because its beauty depends not only on color or size but on the movement of light within the gemstone. Its adularescence can transform an otherwise subtle feldspar into a luminous stone that seems to glow from beneath the surface.
When evaluating moonstone jewelry, pay particular attention to the strength and position of the adularescence, transparency, body color, inclusions, cut, gemstone identity, setting, and overall craftsmanship. If you are shopping online, multiple photographs or video can be especially helpful because the gemstone's sheen changes with the viewing angle.
Moonstone also carries a long history of lunar symbolism, love, renewal, and spiritual meaning. These traditions can add personal significance to the gemstone, while its gemological beauty comes from the natural optical phenomenon that makes moonstone one of the most recognizable members of the feldspar family.
