This substantial unheated Tanzanian green sapphire presents a richly layered colour story across its 6.8x5.8mm cushion face, with a dark, deeply saturated forest green body that shows flickers of olive and warm teal as the stone moves in the light. The multi-tonal character is a hallmark of natural Tanzanian parti corundum, where complex mineral chemistry creates fascinating interplays of cool and warm green tones within a single stone. At 1.40ct it crosses well into the over-one-carat range with a generous face and excellent body depth that reinforces the strong, saturated colour.

Tanzania produces some of the finest natural green sapphires in the world, celebrated for their complex colour zoning and the warm, earthy quality that distinguishes them from the single-tone greens of other origins. This stone is fully unheated and untreated, making its bold natural colour entirely genuine and unenhanced. The cushion cut suits its weight and proportions beautifully, making it an excellent choice for solitaire rings, pendants, and bespoke jewellery pieces for collectors who seek a substantial, natural unheated sapphire with genuine character and colour complexity.
