A Spectrum of Pink
Pink sapphire is corundum coloured by trace amounts of chromium — the same element that, in higher concentrations, creates ruby. Ceylon pink sapphires span a beautiful range from gentle baby pink to vivid, almost neon "hot pink." They've become hugely popular for engagement rings and modern jewellery.
Pink Sapphire vs Ruby
The line between a deep pink sapphire and a ruby is famously blurry and depends on colour intensity. In general:
- More chromium → redder → ruby
- Less chromium → pink → pink sapphire
Different markets draw the line slightly differently, which is one reason certification matters.
What Affects Value
- Colour saturation — vivid, pure pinks are most valued; brownish or greyish tints lower value.
- Clarity — eye-clean stones are preferred.
- Cut & carat — clean larger stones rise steeply in price.
- Treatment — heat treatment is common; untreated certified stones command more.
