2.01ct 7.7mm round orangey pink Opalescent sapphire

2.01ct Orangey Red Opalescent Sapphire, round, 7.7x4mm.

At 2.01ct, this is generous — it'll hold its own in a bold solitaire or side-stone 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.
