1.73 ct Natural Unheated White Sapphire – Radiant Cut

A natural 1.73 carat white sapphire in a radiant cut, colorless and untreated. White sapphire is natural corundum that formed without the trace elements that produce color — the same mineral species as blue, yellow, or pink sapphire but entirely without chromophores. The radiant cut at 1.73 carats produces a stone with strong face-up presence and a modern rectangular silhouette — a format that delivers both architectural clarity and brilliant light return in colorless material.

Good to Know

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

• View it under bright, direct light. Radiant cuts perform best under strong lighting, so assess brilliance in conditions similar to where you'll wear it.
• Consider the setting for an elongated silhouette. At 8.42 x 5.27 mm, this radiant suits an east-west or classic four-prong solitaire setting; confirm your setting accommodates the rectangular outline.
• Confirm treatment status directly when comparison shopping. Untreated stones are the minority of white sapphire on the market, and the term "natural" alone does not guarantee untreated — ask for documentation.
• Weigh availability at this size and treatment status. Untreated colorless sapphire at this size and clarity is a narrower slice of the market than heat-treated white sapphire, which affects both price and availability, as described above.
• Ask for a personal video if you would like to see the stone in motion before finalizing the purchase.
