1.06 ct Natural Unheated White Sapphire – Radiant Cut

A natural 1.06 carat white sapphire in a radiant cut, colorless and untreated. White (colorless) sapphire is corundum without the trace elements that produce color — the same mineral as blue or yellow sapphire, but entirely without chromophores. At Mohs 9, it is substantially harder than any other colorless gemstone alternative to diamond. The radiant cut combines the architectural outline of a rectangular shape with brilliant faceting, producing strong light return in the colorless material.

Good to Know

A few practical points to weigh before purchasing this specific stone:

• View under both daylight and warm indoor light — the radiant cut's brilliant faceting returns light differently than a step or round brilliant cut, so check sparkle under the lighting you'll wear it in most.
• At 6.75 x 5.08mm, this rectangular radiant outline needs a four-prong setting sized for its dimensions rather than a round-stone mounting.
• When comparison-shopping, confirm treatment status in writing — coated or diffusion-treated white sapphire is common in the market, and this stone carries neither.
• Weigh the scarcity noted above, since an untreated, eye-clean white sapphire above 1 carat is harder to source than the broader white sapphire category.
• Ask for a personal video if you would like to see the stone in motion before finalizing the purchase.
