Buying a loose gemstone gives you independence, you get the freedom to make your own choice, your own jewelry design.
This 3.64 carat natural chrysoberyl gemstone is documented by GIA Report #2235922104, which confirms its weight, dimensions, and optical properties. Chrysoberyl ranks 8.5 on the Mohs scale — harder than most gem species outside the corundum family — and occurs in golden-yellow to yellow-green tones; this stone is graded green-yellow. At 3.64 carats, this is a substantial collector-grade piece; well-cut chrysoberyl above 3 carats is genuinely uncommon in the market.
Expert Opinion
Ahmed Shareek's Assessment
"A 3.64 ct chrysoberyl is genuinely large for the species — most of what comes through our hands is well under a carat, and clean, well-cut stones above 3 carats simply don't turn up often. This one is also completely untreated, which is typical for chrysoberyl but still worth confirming on paper, and the GIA report backs it up alongside the size and clarity."
Rarity Analysis
Chrysoberyl is a distinct, comparatively minor gem species next to sapphire, and within that already-small supply, a stone with this combination of size, color, and documentation is harder to find than any single factor suggests on its own.
-
Color: Chrysoberyl's color range runs from golden-yellow through yellow-green. This stone's green-yellow grade sits toward the cooler, more saturated end of that range, which shows up less often than the more common honey-yellow tones.
-
Size: Most faceted chrysoberyl sold is under 1 carat. At 3.64 carats, this stone is well above typical market size — well-cut chrysoberyl above 3 carats is genuinely uncommon, since large clean rough is more often cut into cat's-eye cabochons than faceted stones of this size.
-
Treatment: Chrysoberyl is naturally almost always untreated — unlike sapphire, where the majority of commercial material is heat treated. So untreated status by itself isn't what sets this stone apart from other chrysoberyl; what's harder to find is untreated origin paired with this carat weight and clarity.
-
Documentation: A GIA report on a 3.64 ct chrysoberyl independently confirms species, weight, dimensions, and treatment status. Much of the chrysoberyl sold at this size and price point online carries no third-party lab documentation at all.
-
Combined effect: No single factor here — color, size, or certification — is extraordinary for chrysoberyl on its own. What makes this particular stone hard to replace is finding all three together in one eye-clean, well-cut piece.
Buying Guidance
A few practical points to weigh before purchasing this specific stone:
-
View it under more than one light source. The modified brilliant crown will show active scintillation, while the step-cut pavilion beneath it returns broader, more open flashes of color — an unusual hybrid faceting style that's worth seeing in daylight and warm indoor light before you decide.
-
Check your setting against the actual dimensions. At 9.86 x 8.21 x 6.11 mm, this oval works well as a ring center stone or pendant focal point, but confirm your prong or bezel spacing against these measurements before committing to a mounting.
-
Verify treatment and documentation on any stone you compare this to. Chrysoberyl is usually untreated, but "usually" isn't the same as verified — make sure any seller states treatment status explicitly and can back it up with independent lab paperwork.
-
Don't expect to find a direct replacement quickly. Given how infrequently chrysoberyl of this size and clarity comes to market, comparable inventory is not something you can count on restocking on a predictable timeline.
-
Use the Try Before You Buy option if you would like to see the stone in hand before finalizing the purchase.
