Grandidierite 5.32ct Cushion cut

A natural grandidierite in a 5.32ct cushion cut, 11.9x9.1mm, from Madagascar. The stone shows a medium teal-green body colour with strong yellowish-green matrix patches distributed across the crown, giving it a complex, varied hue. Semi-transparent with dark crystal inclusions visible within the stone. The green tones shift between cooler teal and warmer yellow-green as light moves across the facets, as documented in the product photos.

Grandidierite from Madagascar is among the rarest faceted gem minerals available. This larger cushion example shows the species' characteristic trichroism - the stone can appear blue-green, yellow-green, or near-colourless depending on viewing angle. Untreated, natural. The inclusions and matrix are inherent to the species at this quality level. Suited for a collector or feature jewellery piece.
