0.45ct 4.5mm round Opalescent sapphire purple-pink

0.45ct Purplish Pink Opalescent Sapphire, round, 4.5x3mm.

At 0.45ct, this works as a petite accent, stacking ring stone, or pavé placement.

The opalescence in these sapphires comes from light scattering off fine oriented inclusions within the crystal — silk that gives the surface a soft, diffuse glow rather than the sharp reflection you'd expect from a clean stone. It's a physical property of the microstructure, not a treatment effect, and it's what makes these stones a different proposition from standard pink or purple sapphires.

Treatment: Heated (Beryllium/Superheat/Other). Clarity: Included - hazy or silk inclusions visible to the naked eye. Origin: Madagascar.
