0.98ct 6.4x4.7mm oval purplish pink milk sapphire

0.98ct Purplish Pink Opalescent Sapphire, oval, 6.4x4.7x3.8mm.

At 0.98ct, this is a workable centre stone for a delicate solitaire setting.

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: None — unheated and unenhanced. Clarity: Included - hazy or silk inclusions visible to the naked eye. Origin: Tanzania.
