White sapphire is the diamond alternative in natural corundum — a colorless, durable, brilliant stone at a fraction of diamond prices. This collection features our white sapphires of one carat and above, sized generously enough to anchor an engagement ring on their own or serve as a standout diamond substitute.
Why white sapphire over 1 carat
White (colorless) sapphire is corundum with essentially no trace elements to impart color, and larger stones show off its brilliance and durability (9 on the Mohs scale, second only to diamond) most convincingly — which is why the one-carat mark matters for this stone. Sourced primarily from Sri Lanka (Ceylon).
Clarity and cut. Look for a clean, well-cut stone — white sapphire's brilliance depends heavily on cut quality, since it lacks color to distract from inclusions.
Treatment. Both heated and unheated stones appear in this collection; treatment status is disclosed plainly on every product page.
A diamond alternative. White sapphire is a popular, budget-conscious choice for engagement rings and diamond-look jewelry, offering genuine durability without the diamond price tag.
