0.79ct 6x5.2mm oval Opalescent sapphire pinkish purple

0.79ct Pinkish Purple Opalescent Sapphire, oval, 6x5.2x2.5mm.

At 0.79ct, 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: Madagascar.
