1.01 ct Natural Tsavorite Garnet, Cushion Shape | AGCL Report #M263503

A natural 1.01 carat tsavorite garnet, shape Cushion, accompanied by AGCL (Arctic Gem Certification & Laboratory) Report #M263503, which records the stone's weight, measurements, shape and species. Tsavorite is the green variety of grossular garnet, a calcium aluminium silicate colored by trace vanadium and chromium in the V³⁺ and Cr³⁺ states (Journal of Luminescence 277, 2025; Minerals 13(5) 639, 2023).

Where This Tsavorite Comes From

Tsavorite forms in the Neoproterozoic Mozambique Belt, and the deposits described in the peer-reviewed literature lie in Kenya, Tanzania and Madagascar (Feneyrol et al., European Journal of Mineralogy 26(2), 2014) — a statement about where the material occurs, not about where this particular stone was mined.

This stone: Kenya, on Crescent Gems' purchase record. That is our own record of where we bought it. It is not addressed by the AGCL report and must not be read as a laboratory determination.

Buying Guidance

A few practical points to weigh before purchasing this specific stone:

• Understand what this listing attributes to the report, and what it does not. AGCL Report #M263503 is cited on this listing for the stone's weight, measurements, shape and species. Crescent Gems has not published the report's full scope on this page, so treat the color, clarity, transparency, treatment and origin descriptions here as Crescent Gems' own assessment rather than laboratory findings.
• Treatment is seldom the question here — identity usually is. AGTA's Gemstone Information Manual records tsavorite under code N, defined as "Natural: No modification (or currently has no known modification process)". That is a statement about the variety, not a finding about this stone. Our own assessment is that this stone is untreated. The check that matters more is identity: a laboratory report recording grossular garnet establishes that the stone is tsavorite and not one of the other green garnets sold under the name.
• Choose a protective setting. Mohs 7-7.5 is a scratch-hardness figure for the species and says nothing about how a stone takes a knock; that is toughness, a separate property. GIA's published care guidance describes the garnet group as having "fair to good" toughness and cautions that garnet "should not be subjected to any hard blows or rough wear" — statements about garnet, not findings on this stone's report, and GIA publishes no defined toughness scale, so the wording is quoted as published. For a stone going into a ring, we recommend a bezel or another mounting that shields the girdle edge. That recommendation is Crescent Gems' own — GIA publishes no setting guidance for garnet.
• Check the report against the stone. Read the weight and the measurements off the report and match them to the stone in front of you before finalizing any loose gemstone purchase.
• Use the Try Before You Buy option if you would like to see the stone in hand, under your own lighting, before finalizing the purchase.

Why Choose this 1.01 ct Cushion Tsavorite Garnet?

AGCL Report #M263503 is cited here for the identification and the measurements: grossular garnet, variety tsavorite, 1.01 carats, 5.66 × 5.12 × 4.32 mm, shape Cushion. That is the whole of what this listing attributes to the report.

Everything in this paragraph is Crescent Gems' own description and none of it is a laboratory grade. The stone reads to us as a vivid green. We describe the clarity as minor inclusions under 10× magnification. And our own assessment is that the stone is untreated — that assessment is ours, and it is not presented as a finding on the report.

Key Points of this Natural Tsavorite Garnet

• AGCL Report #M263503
  Cited on this listing for species, variety, weight, measurements and shape.
• Untreated in Our Own Assessment
  AGTA's Gemstone Information Manual records tsavorite under code N, defined as "Natural: No modification (or currently has no known modification process)". That is a statement about the variety, not a finding about this stone. Crescent Gems' own assessment is that this stone is untreated.
• 1.01 Carats, 5.66 × 5.12 × 4.32 mm
  The weight and measurements this listing takes from the report.
• Shape Cushion
  The shape field. The crown and pavilion cutting styles are not recorded on this listing, and a shape word is not a cutting style.
• Mohs 7-7.5, Toughness "Fair to Good"
  Published figures for the species and for the garnet group, not findings on this report. Mohs measures resistance to scratching; toughness is the separate property that describes how a stone resists chipping and breaking. GIA publishes no defined toughness scale, so its wording is quoted as published.
• January Birthstone
  January is the garnet group's traditional birthstone month, a trade convention rather than a finding on this report.

A Single Stone

This is a natural gemstone, untreated in Crescent Gems' own assessment. This is a single natural stone — once it is sold it cannot be reordered or reproduced.

Care of Your Tsavorite Garnet

GIA publishes care guidance for garnet: warm soapy water is always safe, ultrasonic cleaners are usually safe with an exception, and steam cleaning is not recommended. GIA also says garnets "should not be subjected to any hard blows or rough wear". That guidance is about the garnet group and is not a finding on this stone's report.

We go further than GIA on one point: we do not put this stone in an ultrasonic cleaner. That is Crescent Gems' own preference, not GIA's guidance.

• Clean with lukewarm water and mild soap using a soft brush
• Do not use an ultrasonic cleaner on this stone — our own preference, stricter than GIA's
• Do not steam clean — GIA does not recommend steam cleaning for garnet
• Remove before heavy physical activity — GIA's caution for garnet is that it "should not be subjected to any hard blows or rough wear"
• Store separately from harder gemstones to prevent surface scratching — at Mohs 7-7.5 garnet scratches and abrades more readily than corundum at Mohs 9, and scratch resistance is what the Mohs scale measures
• Garnet has no cleavage (Perkins et al., Mineralogy) — this is cited to the mineralogical literature and is not a finding on this report
