White Sapphires

A white sapphire is a colourless to very pale sapphire. It is corundum, the same mineral as blue sapphire, with almost no colour-giving trace elements. It is natural, very hard, and often chosen as a clear stone for rings.

For many buyers, yes. White sapphire is natural, hard enough for daily wear, and costs far less per carat. It looks softer than diamond, with less fire. Choose it for a quiet, clear stone, not for diamond's flash.

Many are. Heat is the common finish for sapphire of every colour, and it is accepted when disclosed. Unheated white sapphires exist and are scarcer. Every Crestonne listing states the treatment, and the certificate confirms it.

Yes. "Ceylon sapphire" describes sapphire originating from Sri Lanka; the term itself does not automatically mean that every stone is untreated. Ceylon sapphires can be natural and may or may not have undergone treatments such as heat treatment. Treatment status should be verified through appropriate gemological testing and disclosure.

Any serious one should be, and ours all are. We use independent labs: TGL (GIA alumni), Guild or GIC. The report states what the stone is, whether it was treated and, where tested, its origin. If a seller claims Ceylon with no report, treat it as marketing.

From a specialist who shows certification and states treatment plainly. That could be Colombo or Ratnapura if you can travel, an auction house, or an origin-direct dealer like Crestonne. Every stone in our collection is certified, bought at the source, with its report number published.
