DETAILED GEMOLOGICAL COMMENT
To accurately determine the mining region, the gem report should be supplemented with Raman microscope study, obtaining the spectrum of these hessonites garnets, and comparing it with the base spectrum of hessonites garnets from Tanzania.
Considering the characteristics of these hessonites:
Weight: …………………….…… 2.33 ct (0.785сt | 0.785ct | 0.745ct)
Сut: ……………………….………………………….……………. oval
Color / Saturation: …….. reddish orange | medium color saturation
Clarity: …………..… slightly included | eye clean | slightly included
Geographic Origin: …………………………….…………… Tanzania
Treatment: …………………….….……. No indication of treatment
Recommended market value corridor (retail price) of Hessonites garnets from Tanzania weighing from 2 carat, slightly included clarity, and reddish orange color, as of 14.02.2026:
350-400 $ per 1 ct
Note: the recommended market value corridor in indicated on this date. The price may change over time. The value corridor is an opportunity for the buyer/ seller to get an objective assessment of the value of this stone. With the receipt of new gemological research data, the cost corridor may be revised.
