Digital marketplace Gembridge has launched a collection of extremely rare, responsibly sourced zoisites in a variety of colours.
11.19-ct bi-colour zoisite
The collection comprises 14 stones, 13 of which are very rare and “no heat”, including green, pinkish/ orange, yellow/ pink, blue, yellow, purple and bi-colour stones.
The 27.29-ct greenish blue, 21.09-ct pinkish yellow, 19.97-ct green and 11.19-ct bi-colour are standouts in the collection.
27.29-ct greenish blue zoisite
The zoisites were collected over a decade, and are unlikely to be repeated, Gembridge says.
21.09-ct pinkish yellow zoisite
The likely buyers of the stones would be collectors of rare, fine gemstones.
19.97-ct green zoisite
The stones, mined in the Meralani district of northern Tanzania, the only known source of gem quality tanzanites and coloured zoisites, were sourced from medium to large scale mining companies in Tanzania.
All such mined stones are exported strictly in accordance with Tanzanian law.
“No heat” zoisite is incredibly rare and as such, the market price outlook is expected to be constructive, Gembridge says.
3.38-ct green zoisite
