Can I see loose unheated sapphires before I choose one?

Yes — that's how we work. Book a viewing or just walk in, sit down with the actual stones, and we'll discuss origin and treatment on every unheated sapphire.

How do I know a sapphire is truly unheated?

Unheated sapphire keeps its colour with no heat treatment at all — the connoisseur's choice — and the only way to be sure is a lab report that states 'no indications of heating'. That's how we sell them, with the report in hand. At 9 on the Mohs scale they're flawless everyday ring stones.
