Yellow Sapphires

A yellow sapphire is corundum, the same mineral as blue sapphire, coloured yellow by traces of iron. The colour runs from pale lemon to golden and vivid canary. It is natural, hard enough to wear every day, and it is the stone known in India as pukhraj. Sri Lanka is one of its main sources.

Most sapphires on the market are heated, whatever their origin. It is a stable practice that goes back centuries, and the trade accepts it as long as it is disclosed. Sri Lanka also produces a good share of stones fine enough to sell unheated, which adds to the island's standing.

Not better. Rarer. Heat brings out the colour in stones that need it, and an unheated stone simply never needed it. When the report confirms no heating, buyers pay roughly two to five times more for that rarity. Beauty is still judged stone by stone.

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.
