Blue Spinel from Tanzania 8.45 Carats Unheated Round

Natural blue spinel from Tanzania weighing 8.45 carats, round in shape, with a brilliant-cut crown and a modified step-cut pavilion. Tanzania is one of the richest gem sources on the planet; its spinels come from several localities, including Mahenge and Tunduru.

Its blue colour, of medium saturation and medium tone, is entirely natural: the stone has undergone no heat treatment, as confirmed by its Lotus Gemology (Bangkok) certificate, which includes an origin determination of Tanzania.
