Moonstone is one of the most misunderstood gemstones when it comes to value. Casual buyers often assume it’s inexpensive because they’ve seen it in budget jewelry — then discover that a single high-quality blue moonstone cabochon can cost more than a small diamond. Others overpay for synthetic or low-grade material sold as premium.
The truth is that moonstone price spans an enormous range — from $5 per carat for standard quality to $500+ per carat for the rarest blue-flash specimens. Knowing where your stone sits on that scale, and why, is what this guide is for.
We cover what moonstone is actually worth, what drives the price difference between a $15 and a $500 piece, a full pricing chart by quality and type, and how to make sure you’re buying real moonstone rather than an imitation.

What Is Moonstone? Why the Price Range Is So Wide
Moonstone belongs to the orthoclase feldspar mineral family. Its defining characteristic — the quality that determines most of its value — is called adularescence: the billowing, floating glow that appears to move beneath the stone’s surface, resembling light reflected on water.
This optical effect is caused by the diffraction of light as it passes through alternating microscopic layers of orthoclase and albite feldspar within the stone. When those layers are extremely thin, they scatter blue wavelengths preferentially — producing the electric blue flash that commands the highest prices. When the layers are thicker, the adularescence appears white or silver, which is more common and less valuable.
The reason the price range spans 100x from bottom to top is simple: the factors that create premium moonstone — exceptional clarity, vivid blue adularescence, no inclusions, significant carat weight — are genuinely rare. The vast majority of moonstone on the market sits in the middle and lower ranges.
What Determines Moonstone Value — The 6 Key Factors
1. Adularescence Intensity
This is the single most important factor. A strong, vivid, floating glow dramatically increases value. Weak or patchy adularescence — where the effect is dull or only visible at certain angles — reduces value significantly. The best moonstones show a blue glow that shifts and rolls when the stone moves, visible from multiple angles.
2. Colour of the Flash
Blue adularescence is the most prized, followed by silver-white, then any secondary colour tones. The body colour of the stone also matters — colourless or very lightly tinted bodies with blue flash are the premium standard. Peach, grey, yellow, and green body colours are more common and less valuable, though peach moonstone has its own following for its warm, feminine quality.
3. Clarity
Eye-clean moonstones — those with no visible inclusions when viewed without magnification — command the highest prices. Moonstone characteristically contains “centipede” inclusions: stress fractures resembling many-legged insects visible under magnification. Minor inclusions are acceptable in premium stones; visible cloudiness or prominent fractures reduce value substantially.
4. Cut
Nearly all high-quality moonstone is cut as a cabochon — a smooth, domed shape with a flat base — because this cut best focuses and displays adularescence. The dome height matters: too flat and the glow diminishes; too high and the stone becomes impractical for setting. A well-proportioned cabochon that positions the blue flash at the top of the dome is worth significantly more than a poorly cut stone with the same raw material.
5. Carat Weight
Large, high-quality moonstones are disproportionately rare. A blue adularescent moonstone above 5 carats commands exponentially higher prices per carat because the material quality required to produce that effect in larger sizes is extremely scarce. Blue moonstones rarely exceed 15–20 carats at high quality.
6. Origin
Origin influences both quality and price. Sri Lankan moonstones (particularly from Meetiyagoda) are historically considered the finest, known for their colourless bodies and vivid blue flash — though the best material from this source is increasingly depleted. Indian moonstones are abundant, well-cut, and affordable. Burmese moonstones historically produced the finest blue-flash material but that source is now largely exhausted.

How Much Is Each Type of Moonstone Worth?
Blue Moonstone
The most valuable variety. A true blue moonstone has a colourless or near-colourless body with a vivid, floating blue adularescence that shifts across the dome as the stone moves. Sri Lankan origin, eye-clean clarity, and strong centred blue flash are the markers of collector-grade specimens.
Price range: $50 – $500+ per carat. Fine specimens above 5 carats regularly sell for $200–$500 per carat. Museum-quality pieces exceed this significantly.
Rainbow Moonstone
Technically a variety of labradorite rather than true orthoclase moonstone, but accepted in the gem trade under this name. Rainbow moonstone shows multicoloured labradorescence — blue, green, and sometimes orange — against a near-transparent white body. Highly desirable for jewellery for its visual complexity.
Price range: $15 – $60 per carat. More available than fine blue moonstone, and slightly lower priced for equivalent size, but visually spectacular material can approach blue moonstone prices.
White / Colourless Moonstone
The most commonly available quality range. White adularescence against a white or near-white body, eye-clean with a clean dome. This is what most mainstream moonstone jewellery uses. Good-quality material from India and Sri Lanka is widely available at accessible prices.
Price range: $10 – $50 per carat for retail-quality material.
Peach Moonstone
Warm peachy-orange body colour with white or slight orange adularescence. Particularly popular for its warm, feminine quality and traditional association with the sacral chakra and emotional healing. Less rare than blue but has a devoted following.
Price range: $8 – $25 per carat.
Cat’s Eye Moonstone
Rare — moonstone that shows chatoyancy (a moving line of light across the dome) in addition to adularescence. The combination of two optical phenomena in one stone is exceptional. Sri Lankan cat’s eye moonstones are among the most collectible examples of the species.
Price range: $50 – $200+ per carat depending on clarity and effect strength.
Raw Moonstone vs Cut Stone vs Jewellery — Price Comparison
| Form | Price Range | Best For | Notes |
|---|---|---|---|
| Raw / rough moonstone | $1 – $20 per gram | Collectors, crystal healing, display | Quality hard to assess without cutting; adularescence often masked in rough |
| Cut cabochon (loose) | $5 – $500+ per carat | Jewellery makers, collectors | Best way to evaluate true quality; adularescence fully visible |
| Set in silver jewellery | $25 – $800+ | Wearers, gift-givers | Most common retail form; sterling silver setting typical |
| Set in gold jewellery | $150 – $3,000+ | Fine jewellery buyers | Gold setting + fine stone; significant craftsmanship premium |
| Carved / figurative | $5 – $100 | Decorative, spiritual objects | Near-opaque material; value in carving artistry more than stone quality |
Real vs Fake Moonstone — How to Tell
The most common imitations are milky chalcedony (a quartz variety) and certain types of synthetic opalescent glass. Both attempt to replicate the floating-glow quality of true adularescence. Here’s how to distinguish genuine moonstone:
- Adularescence moves in 3D. Real moonstone’s glow appears to float beneath the surface and shifts as the stone moves. Glass and chalcedony imitations produce a flat, surface-level sheen without the floating depth.
- The glow follows the dome. In a well-cut genuine moonstone, the adularescence centres at the top of the cabochon. In imitations it often distributes more uniformly or appears as a simple surface reflection.
- Real moonstone has centipede inclusions. Under magnification, authentic moonstone often shows distinctive “centipede” stress fissures — pairs of cracks resembling many-legged insects. These are diagnostic and won’t appear in glass or synthetic material.
- Weight and coolness. Real moonstone feels heavier and stays cooler longer in your hand than glass imitations, which warm quickly.
- Refractive index. A gemologist with a refractometer can confirm moonstone’s characteristic RI of 1.518–1.525 — distinct from glass or chalcedony.
Note: Lab-created moonstone is not currently available commercially in meaningful quantities. When moonstone is described as “synthetic,” it almost always means an imitation — chalcedony, glass, or opalescent acrylic — not a genuine lab-grown version of the mineral.
Where Moonstone Comes From — Origin & Value
| Origin | Quality Profile | Value Impact |
|---|---|---|
| Sri Lanka | Colourless body, vivid blue flash — finest quality globally | Highest premium — commands 20–50% over Indian equivalent |
| Myanmar (Burma) | Historically finest blue-flash material; source now largely depleted | Very high — rare, mostly in collector circulation |
| India | Abundant, well-cut, good body colour range; often peach, orange, grey | Mid-range — excellent value, most retail moonstone |
| Madagascar | Increasingly important source; produces rainbow moonstone (labradorite) | Mid-range to high for fine rainbow material |
| Tanzania / Australia / USA | Smaller quantities; variable quality | Standard to mid-range |
Is Moonstone Worth Buying? Practical Buying Guide
Whether moonstone is “worth it” depends entirely on what you’re buying it for. Here’s a practical breakdown:
For Spiritual and Crystal Healing Use
Moonstone is one of the most meaningful healing stones available — connected to lunar energy, intuition, and the sacral and crown chakras. For crystal healing purposes, mid-grade to high-grade white or peach moonstone provides the full energetic benefit at accessible prices ($10–$40 per carat). You don’t need blue flash for the stone’s energetic properties — the adularescence quality affects monetary value, not spiritual resonance.
Moonstone works particularly well alongside other crystals for emotional balance and intuition. For a guide to healing stones and how to wear them effectively, see our complete healing bracelets guide →
For Jewellery Investment
Fine blue moonstone, particularly large Sri Lankan specimens above 5 carats, has appreciated consistently as the best material from historical sources (Myanmar, Sri Lanka) becomes scarcer. Collector-grade blue moonstone is a legitimate gemstone investment — though as with any gemstone, authentication from a qualified gemologist (GIA, AGL) is essential before spending significant money.
For Gift-Giving
Moonstone is one of the most universally meaningful gift stones — associated with the Moon, with new beginnings, with feminine energy and intuition. Mid-grade white or peach moonstone jewellery in sterling silver is an excellent, genuinely beautiful gift at accessible price points. For crystal gift inspiration across all budgets, see our gifts for crystal lovers guide →
Moonstone as a June Birthstone
Moonstone is one of three official birthstones for June (alongside pearl and alexandrite). This makes it a particularly meaningful gift for June birthdays — and demand spikes appropriately in late spring. Buying outside peak season (September–February) often yields better prices and selection from reputable dealers.
Tips for Buying Moonstone at a Fair Price
- See adularescence in person when possible. Photographs rarely capture the depth and movement of real adularescence. A stone that looks mediocre in photos may be extraordinary in person, and vice versa. Ask vendors for video of the stone moving in light.
- Ask specifically about origin and treatment. Sri Lankan moonstone commands a premium — verify claims with documentation. Surface coating (to enhance adularescence) is an occasional treatment; treated stones should be disclosed and priced accordingly.
- Price by the carat for loose stones. When comparing loose stones, standardise by price per carat to make meaningful comparisons. A heavier stone at a lower total price may cost more per carat than a smaller, finer one.
- For fine specimens, request gemological documentation. Any moonstone above $500 total value warrants a certificate from a recognised gemological laboratory (GIA, AGL, or Gübelin) confirming natural origin, origin if claimed, and any treatments.
- Know what you’re comparing. “Rainbow moonstone” is technically labradorite — genuinely beautiful and worth buying, but a different mineral from orthoclase moonstone. Both are sold honestly under their respective names; problems arise only when one is misrepresented as the other.
Moonstone’s Spiritual Value — Beyond the Price Tag
For practitioners of crystal healing, yoga, and meditation, moonstone’s worth extends well beyond its gemological market price. It is the lunar stone — connected across cultures to the Moon’s cyclical energy, to feminine intuition, and to the emotional body’s capacity for reflection and renewal.
In chakra work, moonstone resonates with both the crown chakra (higher consciousness, spiritual connection) and the sacral chakra (emotional fluidity, creativity, intuition). It is particularly used during new moon rituals, emotional processing work, and any practice oriented toward deepening inner knowing.

Moonstone is also traditionally associated with Reiki healing practice, where it is used to support the flow of gentle, receptive energy. See our Reiki gifts guide → for how moonstone fits into a broader healing practice.

Frequently Asked Questions
How much is moonstone worth per carat?
Moonstone price per carat ranges from under $5 for commercial-grade opaque material to $500+ per carat for rare, large, eye-clean blue adularescent stones from Sri Lanka. The most common quality range — white or peach moonstone with moderate adularescence — sells for $10–$30 per carat. Premium white moonstone runs $20–$80 per carat, and fine blue moonstone $50–$250+ per carat depending on size and adularescence quality.
Is moonstone expensive compared to other gemstones?
At the middle market, moonstone is very accessible — comparable to or less expensive than good amethyst, citrine, or blue topaz. At the premium end, fine blue moonstone rivals tanzanite, alexandrite, and sapphire in per-carat price. The stone spans an enormous quality range, making it available at almost any budget — the key is knowing which quality tier you’re shopping in.
How much is a blue moonstone worth?
Blue moonstone — meaning genuine orthoclase moonstone with vivid blue adularescence against a colourless body — is worth $50–$500+ per carat depending on size, intensity of flash, and clarity. Small (1–3 carat) high-quality blue moonstone cabochons retail for $50–$200. Stones above 5 carats with strong blue flash from Sri Lanka can reach $200–$500 per carat and command collector premiums.
How much is rainbow moonstone worth?
Rainbow moonstone (technically labradorite with multicoloured adularescence) typically sells for $15–$60 per carat for high-quality material. Fine large stones with vivid multicolour flash can reach $100+ per carat. At the retail jewellery level, a sterling silver rainbow moonstone pendant or ring runs $30–$200 depending on stone size and craftsmanship.
Is raw moonstone worth more or less than cut moonstone?
Cut moonstone is generally worth more per carat than raw rough for the same quality of material because cutting reveals and focuses the adularescence that is largely hidden in uncut rough. However, raw moonstone is significantly cheaper to buy per gram — the difference accounts for cutting labour and material loss during cutting (typically 50–70% of rough weight is lost). For healing and spiritual use, raw moonstone is equally effective and more affordable.
How can I tell if my moonstone is valuable?
The main indicators of a valuable moonstone are: vivid, floating adularescence that moves and shifts (especially blue); a near-colourless or colourless body; no visible inclusions; significant carat weight (above 5 carats); and confirmed Sri Lankan or Burmese origin. If your stone shows strong, centred blue flash, is eye-clean, and weighs several carats, it is worth having evaluated by a qualified gemologist. For most decorative or healing-use moonstone, mid-grade quality is both sufficient and significantly more affordable.
