1.42 ct Natural Unheated White Sapphire – Round Cut

A natural 1.42 carat white sapphire in a round cut, colorless and untreated. White sapphire is corundum without chromophore trace elements — the same mineral as blue, pink, or yellow sapphire, but entirely colorless. At Mohs 9, it is the hardest colorless gemstone alternative to diamond. At 1.42 carats in a round cut, this stone has the size and format that most directly replaces a diamond in a standard solitaire setting — without the diamond price point.

Good to Know

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

• View in both daylight and warm indoor light — colorless stones can pick up faint warmth from surrounding metal, so check the stone under the lighting you'll wear it in most.
• At 7.40 x 7.34mm, this stone sits comfortably in a standard 4- or 6-prong solitaire head sized for a diamond of similar face-up diameter, without custom fabrication.
• When comparison-shopping, confirm treatment status in writing — many white sapphires on the market are diffusion-treated or coated, which this stone is not.
• Weigh the scarcity noted above, since genuinely untreated, loupe-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.
