Most visitors come to Tanzania looking for tanzanite.
Few realise that Tanzania is also home to one of the gem world’s most fascinating treasures: colour-change garnet.
In daylight, these remarkable gemstones can appear greenish, grey-green or teal. Under incandescent light, they can transform dramatically to reddish-purple, raspberry or burgundy tones.
The finest examples display a strong, obvious colour change that can be seen with the naked eye, and those are exceptionally rare.
Being on the ground in Tanzania 🇹🇿 gives me the opportunity to view gemstones where they enter the market, assess quality first-hand, and search for the exceptional stones that rarely make it to mainstream jewellery shops.
When sourcing a colour-change garnet, it’s not just about finding one that changes colour. The best stones combine:
💎 Strong colour change
💎 Attractive colours in both lighting conditions
💎 Good clarity
💎 Reliable provenance
These are the details that separate an ordinary stone from one worth owning.
If you’re looking for a truly unusual gemstone for a bespoke jewellery project or collection, colour-change garnet deserves a place on your radar.
