Description
Polychrome tourmaline weighing 19.10 carats has an unusually beautiful color: a smooth transition from rich bluish green to sunny yellow. This palette of colors is not the result of refinement, but the natural color of the mineral. This color gradient is due to the unique chemical composition of the tourmalines.
The modified Octagon cut is ideal for polychrome tourmalines, allowing the cutter to place colors on diametrically opposed parts of the stone.
All characteristics are confirmed by the certificate of the international laboratory ICA GemLab.
The photos and videos of the stone on the hand and in the tweezers are taken in daylight without any filters or color correction. More files on request.
