1.63 CT NATURAL COLOR-CHANGE SPINEL — GIA DOCUMENTED

A distinctive natural spinel for collectors and jewelry buyers, with a GIA report documenting a visible color change from violetish blue to purple under different lighting conditions.

In daylight or fluorescent light, the stone presents a cool violetish-blue appearance. Under incandescent lighting, it shifts toward purple, giving the gem a dynamic look that changes with its surroundings. This makes it an engaging choice for anyone who appreciates gemstones with visual character beyond a single face-up color.

The transparent cushion cut combines a modified brilliant-cut crown with a modified step-cut pavilion. As the stone moves, the faceting produces flashes of blue, violet, and purple while preserving the elegant outline of a cushion-shaped gem.
