The Clear, Durable Alternative
White sapphire is simply colourless corundum — sapphire with no trace elements to give it colour. It is naturally clear, very hard (Mohs 9), and Sri Lanka is a notable source of fine natural white sapphires. It has become a popular, affordable alternative to diamond for engagement rings and everyday jewellery.
White Sapphire vs Diamond
- Hardness: Diamond is 10, white sapphire 9 — both excellent for daily wear.
- Sparkle: Diamond has more fire (coloured flashes) due to higher light dispersion; white sapphire has a softer, more silvery brilliance.
- Price: White sapphire is significantly more affordable per carat.
What Affects Value
- Colourlessness — the clearer and more "white" (free of grey or yellow tints), the better.
- Clarity — eye-clean stones are preferred.
- Cut — a precise cut is essential to maximise the stone's brilliance.
Care Tip
White sapphire can show smudges and may need regular cleaning to keep its sparkle. Warm soapy water and a soft brush is usually enough.
