A rare photochromic sapphire that shifts between yellow and intense yellow depending on light exposure — a reversible colour-change effect seen in only a small fraction of natural sapphires. This 1.22 carat Ceylon stone is fully transparent with even colour distribution and strong fluorescence, faceted as a pear to showcase its brilliance. Untreated, with no indications of any treatment, and formed roughly 550 million years ago in the gem gravels of Sri Lanka.

What Makes It Special
This is a true chameleon sapphire — its colour reversibly shifts with prolonged light exposure or its absence, a phenomenon rooted in trace-element interactions within the crystal that very few natural sapphires exhibit. Combined with strong fluorescence and even colour saturation, it's a stone that behaves differently depending on how and where it's worn, making it a genuine conversation piece for collectors as much as a jewel.
