Buying a loose gemstone gives you independence, you get the freedom to make your own choice, your own jewelry design.
A natural 1.07 carat tsavorite garnet in a round cut, completely untreated and documented on AGCL Report #M2513969. Tsavorite is a calcium aluminum silicate (grossular garnet) colored by trace vanadium and chromium, producing vivid jewel-tone greens that rival or surpass the finest emerald in color intensity. It was discovered in 1967 in Kenya's Tsavo region and has never required treatment of any kind — no heating, no oiling, no filling. At 1.07 carats in a round cut, this is a versatile center-stone format in one of the rarest green gemstones available.
Expert Opinion
Ahmed Shareek's Assessment
"Tsavorite is, carat for carat, one of the rarest gemstones I work with — global production is a fraction of what comes out of the emerald or ruby mines, and virtually none of it needs treatment to look this good. This 1.07 ct round is untreated, eye-clean, and shows the kind of saturated, jewel-tone green that collectors specifically seek out in tsavorite. Stones like this don't sit in inventory long."
Rarity Analysis
Tsavorite garnet is a comparatively young discovery in the gem world — first identified in Kenya's Tsavo region in 1967. Unlike most colored stones, tsavorite is almost never treated, so what you see in a natural tsavorite is exactly how it formed. A few factors make this particular stone stand out even within an already-rare species:
-
Color: Vivid Green saturation of this intensity is uncommon in tsavorite — much of the material on the market runs lighter or more yellow-green; strongly saturated, pure green stones like this one command a premium.
-
Size: At 1.07 carats, this stone is above the typical size range for tsavorite, which is most commonly found and sold under 1 carat; larger clean material becomes disproportionately scarce as carat weight increases.
-
Treatment: Untreated — tsavorite is almost universally sold untreated, since there is no commercially accepted treatment that improves its color or clarity. This is standard for the species rather than a rarity driver in itself, but it does mean there is no treatment-disclosure risk with this stone.
-
Clarity: Loupe Clean with no visible inclusions under normal viewing — tsavorite is often heavily included, so eye-clean material at this size is a genuine clarity achievement, not the norm.
-
Documentation: Independently examined and reported by AGCL, Report #M2513969. Origin, Kenya, is the store's own assessment; not addressed by the AGCL report.
-
Combined effect: A large, vividly colored, eye-clean, untreated tsavorite with independent documentation is a genuinely uncommon combination — most tsavorite on the market falls short on at least one of these dimensions.
Buying Guidance
Tsavorite is a gemstone where quality varies dramatically from stone to stone, so a few things are worth checking before you buy:
-
Color saturation: Look for a vivid, evenly distributed green rather than a pale or brownish-green tone — saturation is the single biggest driver of value in tsavorite.
-
Carat weight vs. size: Tsavorite is denser than diamond, so it can look smaller than its carat weight suggests — always check the millimeter dimensions against the setting you have in mind.
-
Treatment disclosure: Confirm the stone is untreated; this is standard for tsavorite, and a seller should state it plainly rather than leaving it ambiguous.
-
Certification: Buy a stone with independent lab documentation, and understand exactly what the report does and does not cover — origin statements, for example, are sometimes the seller's own assessment rather than a lab finding.
-
Try Before You Buy: If you're considering this stone for an engagement ring or other custom setting, ask about viewing it in hand or under different lighting before committing — tsavorite's color can shift meaningfully between daylight and indoor light.

This 1.07 ct round tsavorite garnet has been hand-selected for the vividness and saturation of its green — the quality that makes tsavorite the most compelling green gemstone in terms of color-per-dollar value. Tsavorite's case against emerald is straightforward: equal or greater color intensity, dramatically better clarity (tsavorite is typically eye-clean; emerald is almost always heavily included), more durability, and zero treatment requirement.
One of a Kind
This is a single natural gemstone, not a lab-created or mass-produced stone. No two natural tsavorite garnets are identical — the exact stone pictured is the exact stone you receive.
Care
Clean with warm soapy water and a soft brush; avoid ultrasonic cleaners and harsh chemicals. Although durable at 7–7.5 on the Mohs scale, store separately from other jewelry to prevent scratches and impacts.
