Pink & Purple Sapphires

A pink sapphire is corundum, the same mineral as blue sapphire, coloured pink by traces of chromium. With more chromium the colour turns red, and a red corundum is called ruby. Pink sapphires are natural stones, sold heated or unheated, and hard enough to wear every day.

A purple sapphire is corundum coloured by chromium, which gives pink, together with iron and titanium, which give blue. The mix lands between the two: purple, violet or lavender. Many stones sit between pink and purple. Purple sapphires are natural stones, sold heated or unheated, and hard enough to wear every day.

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.

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.
