Uvarovite
Uvarovite is garnets (nesosilicates), Ca3Cr2(SiO4)3. In the hand, it rates 6.5 to 7 on the Mohs scale, and it runs vivid emerald green and deep chrome green. Carpets of tiny, intensely emerald-green garnet crystals glittering on grey chromite matrix, the only garnet that is always green, and almost always too small to facet.
The geology.
Uvarovite carries the formula Ca3Cr2(SiO4)3. It belongs to the cubic system. Catalogues list it as garnets (nesosilicates).
It sits at 6.5 to 7 on the Mohs scale. The surface reads vitreous, brilliant. Light behaviour is transparent to translucent. Specific gravity runs 3.77 to 3.81. The streak is white. It breaks with no cleavage; conchoidal to uneven fracture.
Carpets of tiny, intensely emerald-green garnet crystals glittering on grey chromite matrix, the only garnet that is always green, and almost always too small to facet.
It reaches buyers as sparkling druzy crusts of tiny dodecahedra, drusy slabs in jewelry or rare single crystals.
The origins.
Chromite deposits, Saranovskii Mine (Urals, Russia) supplies the classic druzy; also Outokumpu (Finland), Turkey, India.
On value, the database notes: mid-range; rich Russian druzy plates are jewelry favorites.
Traditional associations.
In energy work traditions, uvarovite is tied to quiet prosperity and feeling sufficient exactly as things are.
We keep this section because people ask. It sits below the geology on purpose, and none of it describes something the stone does.
Spotting the real thing.
Carpets of tiny, intensely emerald-green garnet crystals glittering on grey chromite matrix, the only garnet that is always green, and almost always too small to facet.
Green glass 'druzy' and dyed quartz crusts imitate it, real uvarovite's crystals are sharp dodecahedra with color all the way through.
| Looks like | How to tell them apart |
|---|---|
| Emerald (crystals) | Emerald grows hexagonal prisms; uvarovite forms 12-sided garnet sparkle-crusts |
| Chrome diopside | Diopside forms elongated cleavable prisms, softer luster |
| Green-dyed druzy | Dyed quartz druzy shows color pooled between crystals and wipes with solvent |
At-home tests.
Before anyone talks you into a lab report, these are the checks worth doing yourself on uvarovite.
| Test | What you should see |
|---|---|
| Scratch check | Dodecahedral micro-crystals, hardness ~7, on dark chromite host |
| By eye | Color is even and intrinsic, no dye in crevices |
| By eye | No cleavage flash, just facet sparkle |
Anything that scratches, burns or dissolves the piece is a lab job. Get it appraised rather than testing it apart.
Care & handling.
At 6.5 to 7 on the Mohs scale it handles careful wear but scratches against quartz and dust. Store it separately and take rings off before rough work.
It breaks with no cleavage; conchoidal to uneven fracture, which is worth knowing before you set it or drop it.
Warm water and a soft cloth clean almost everything. Ultrasonic tanks, steamers and household cleaners are where pieces get ruined.

The physical record
The formula on record is Ca3Cr2(SiO4)3. Crystal system: Cubic. Specific gravity: 3.77 to 3.81. Streak: White. Cleavage and fracture: No cleavage; conchoidal to uneven fracture.
How it reaches the market
Chromite deposits, Saranovskii Mine (Urals, Russia) supplies the classic druzy; also Outokumpu (Finland), Turkey, India.
What it gets confused with
Emerald (crystals): Emerald grows hexagonal prisms; uvarovite forms 12-sided garnet sparkle-crusts. Chrome diopside: Diopside forms elongated cleavable prisms, softer luster. Green-dyed druzy: Dyed quartz druzy shows color pooled between crystals and wipes with solvent.
What it is worth
Mid-range; rich Russian druzy plates are jewelry favorites.
Where buyers get caught
Green glass 'druzy' and dyed quartz crusts imitate it, real uvarovite's crystals are sharp dodecahedra with color all the way through.
One more thing
Named for Count Sergei Uvarov, a Russian statesman-scholar, the Ural mines that supplied tsarist treasures still produce the green druzy that jewelers set whole, since single stones big enough to facet are near-mythical.
An education-first guide.
No product links here. We do not sell uvarovite, and a guide that only covers our own shelves would not be much of a guide.
