1.85 ct Natural Tsavorite Garnet, Cushion Shape | Treated | GIA Report #6243017771

A natural 1.85 carat tsavorite garnet, Cushion shape, with GIA Identification Report #6243017771 recording the species, variety, weight, measurements, shape, both cutting styles, color and transparency. This stone is treated: the report prints Clarity Enhanced under Additional Results. Tsavorite is the green variety of grossular garnet, a calcium aluminum silicate colored by trace vanadium and chromium in the V³⁺ and Cr³⁺ states (Journal of Luminescence 277, 2025; Minerals 13(5) 639, 2023 — GIA itself publishes no chromophore for tsavorite). The color field on this stone's report reads Green.

Treatment: This Stone Is Treated

GIA publishes that its Identification Report states any detectable treatments; this report prints Clarity Enhanced under Additional Results. In plain words, and in this page's own words: the stone is treated.

GIA's own treatment FAQ writes "fracture filling/clarity enhancement" as a single item for colored stones, and GIA defines that process as "filling surface-reaching fractures or cavities with a glass, resin, wax or oil to conceal their visibility and to improve the apparent clarity of gem materials". Two things follow from that, and this page states both rather than resolving either:

• The substance is not stated. GIA's definition admits a glass, a resin, a wax or an oil, and GIA Report #6243017771 does not say which was used on this stone, so this page names none of them. GIA states that "Much depends on the durability of the filler" and that "Glasses tend to be harder and therefore more durable than resins, oils or waxes" — so this page makes no claim about the durability or the permanence of the filling in either direction.
• No degree or level is stated. GIA publishes no grading of the level of clarity enhancement for garnet. The report records the treatment, not an extent, and this page adds no extent of its own.

The treatment changes how the stone must be cleaned. GIA's garnet care page addresses fracture-filled garnet specifically, and its instruction is "Only warm soapy water should be used to clean fracture-filled stones." The whole care instruction is set out under Care of Your Tsavorite Garnet below, and the practical consequences are worth reading before the stone is set.

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). The blurb printed on the GIA report states that "the significant commercial sources for this garnet are Kenya and Tanzania" — a statement about where the trade is supplied from, 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 a GIA determination and must not be read as one: GIA does not offer geographic origin for grossular garnet, so the absence of an origin line on this report is not an option the submitter declined.

Buying Guidance

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

• Understand what this GIA report does and does not cover. Report #6243017771 is an Identification Report. GIA describes that service as one that "identifies and describes a material and lists detectable treatments", and this report lists Clarity Enhanced under Additional Results. It records species (Grossular Garnet), variety (Tsavorite), weight, measurements, shape, both cutting styles, color and transparency. It carries no color grade, no clarity grade, and no origin: GIA does not offer geographic origin determination for grossular garnet at all, so no GIA report on this stone could have carried one. Treat the clarity and origin descriptions on this listing as Crescent Gems' own.
• Plan for the care instruction before you plan the jewelry. GIA's instruction for a fracture-filled stone is warm soapy water only, and GIA separately says to avoid heat, solvents, chemicals, steam, ultrasonic cleaners and changes in air pressure. If a mounting, a resizing or a later repair would need heat or a bench ultrasonic cleaner, that is a real constraint on this stone and it is better weighed now than afterwards.
• Read the shape field and the two cutting-style fields separately. The report prints shape Cushion, crown Brilliant Cut and pavilion Modified Step Cut. Shape is the outline; cutting style is how the facets are arranged, and this report carries one field for each half of the stone. GIA publishes no definition of "Modified", so this page quotes the report's wording and does not gloss it.
• Choose a setting that protects the stone. Mohs 7-7.5 is a scratch-hardness figure and says nothing about how a stone takes a knock; that is toughness, a separate property, printed on this report as "Good" — GIA publishes no defined toughness scale, so the report's word is quoted as printed and is not ranked inside one. GIA's caution for garnet is that it "should not be subjected to any hard blows or rough wear". For a ring we recommend a mounting that shields the girdle edge, with prongs at the corners of the cushion outline rather than at the sides alone. 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 1.85 ct Tsavorite Garnet, Cushion Shape?

The GIA report settles the identification, the measurements and the treatment: grossular garnet, variety tsavorite, 1.85 carats, 7.92 × 6.05 × 4.53 mm, shape Cushion, color Green, transparent, crown Brilliant Cut, pavilion Modified Step Cut, Mohs 7-7.5, toughness "Good", birthstone January given to GARNET as a GROUP and not to tsavorite, and Clarity Enhanced printed under Additional Results. That is the whole of what the report determines.

What is not on the report is marked as ours throughout this page. A GIA colored-stone report carries no color grade and no clarity grade, so the color field above is a description rather than a grade, and the clarity line is Crescent Gems' own: minor inclusions under 10× magnification. The Kenya on this page is our purchase record, not a GIA determination. The treatment is the report's own finding, and the cleaning instruction that follows from it is GIA's.

Key Points of this Natural Tsavorite Garnet

• GIA Report #6243017771
  Dated 3 August 2026. Records species, variety, weight, measurements, shape, both cutting styles, color and transparency.
• Treated — Clarity Enhanced
  The report prints Clarity Enhanced under Additional Results. GIA's treatment FAQ writes "fracture filling/clarity enhancement" as one item and defines the process as filling surface-reaching fractures or cavities with "a glass, resin, wax or oil". The report does not state which, and this page names none.
• Warm Soapy Water Only
  GIA's garnet care page: "Only warm soapy water should be used to clean fracture-filled stones." No ultrasonic, no steam, no heat, no solvents and no household chemicals.
• 1.85 Carats, 7.92 × 6.05 × 4.53 mm
  The weight and measurements printed on the report.
• Cushion, Crown Brilliant Cut, Pavilion Modified Step Cut
  The shape field and both cutting-style fields, as printed on the report. GIA publishes no definition of "Modified", so the report's wording is quoted and not glossed.
• Color Green, Transparent
  Both as printed on the report. A GIA colored-stone report carries no color grade.
• Mohs 7-7.5, Toughness "Good"
  From the report's Characteristics panel. 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 the report's word is quoted as printed.
• January Birthstone of the GARNET GROUP
  The report's Characteristics panel prints Birthstone: January. January is given to GARNET as a GROUP and is not a finding about tsavorite.

Care of Your Tsavorite Garnet

GIA publishes a care instruction for a stone like this one, and it is narrower than GIA's general guidance for garnet. GIA's garnet care page addresses fracture-filled garnet specifically: "Only warm soapy water should be used to clean fracture-filled stones." On the same page GIA states that steam cleaning is not recommended for garnet at all, that the ultrasonic cleaner is "usually safe except for stones that have fractures", and that garnets "should not be subjected to any hard blows or rough wear". For treated gems generally GIA states that the treatments "can be negatively affected by heat, solvents, steam and ultrasonic cleaners", and for a filled stone GIA says to "avoid exposure to heat, and changes in air pressure (such as in an airline cabin), or chemicals".

Separately from the treatment, GIA's journal Gems & Gemology named tsavorite among "heat-sensitive stones" in Summer 1987 (Deborah Dupont Martin, "Gemstone Durability: Design to Display", Gems & Gemology, Summer 1987, pp. 63-77).

• Clean with warm soapy water only — GIA's instruction for a fracture-filled stone
• Do not use an ultrasonic cleaner — GIA's ultrasonic exception for garnet is stones that have fractures, and GIA separately says not to use one on a filled stone
• Do not steam clean — GIA does not recommend steam cleaning for garnet, treated or not
• Keep the stone away from heat — GIA says to avoid exposure to heat for a filled stone, and Gems & Gemology named tsavorite itself heat-sensitive in Summer 1987
• Keep the stone away from solvents and household chemicals — GIA names solvents and chemicals for treated and filled gems
• Avoid changes in air pressure — GIA's own example is an airline cabin
• 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

One request of our own, which GIA does not publish. We ask that you tell any jeweller or bench that this stone's report prints Clarity Enhanced, before any repair, resizing, setting or cleaning work. GIA publishes no exemption for a professional's ultrasonic cleaner — its prohibitions are stated by treatment, not by who operates the machine — and its own 1987 guidance in Gems & Gemology is that "No repair should be attempted with the stone in place until the gem has been identified" and that "If you cannot determine with certainty whether or not a stone has been enhanced, assume that it has and take the more conservative approach". That request is Crescent Gems' own, not GIA's.
