4.38CT Color Change Garnet


A stunning color changing garnet from Tanzania. With a GIA Certificate this is a clean, well-cut and exception color-change garnet. Hailing from Nandagala in Tanzania this material is old stock from around 2011/2012, and is HIGHLY COLLECTIBLE.

The colors are very susceptible to light-temperature and can exhibit green, blue and light-violet under the cooler-parts of the light-spectrum, and change to pinkish to intense violet with orange and red flashes under the warmer parts of the spectrum. Outdoors, the colors constantly change from blue-green to orangey-red with time of day, cloud cover and sunlight intensities. A superb rare crystal that is twitching with color change.

Clarity Explainer

Internally Flawless crystals occur infrequently and the market-reality is they are actually unusual. VVS is where most ‘clean’ gems fall on the clarity scale, and VS can be thought of as ‘eye clean at jewelry viewing distance (30cm+)’. With SI and I becoming included. Pls read the Clarity page for more info.


Our gemstones are vetted during purchasing by highly experienced gemologists, and then formally tested in our own lab. Many of our gems are also awarded reports by independent gem labs — making a triplicate of gemological security.
