1.13 ct Natural Unheated White Sapphire – Radiant Cut | AGCL Certified | Sri Lanka (Ceylon)

A natural 1.13 carat white sapphire in a radiant cut, colorless and untreated, documented on AGCL Report #M263118. Radiant-cut colorless sapphire at 1.13 carats is a practical, modern diamond alternative — the radiant's cropped corners and brilliant faceting produce strong light return in colorless material, and the rectangular silhouette gives it a more structured, contemporary look than a round brilliant. At Mohs 9, white sapphire is the hardest colorless gemstone alternative to diamond, fully appropriate for daily ring wear.

Good to Know

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

• Setting compatibility: at 6.3 x 4.86 mm, this radiant cut needs a setting sized for its rectangular outline, not a round mounting — confirm with your jeweler or use our custom ring service.
• Diamond alternative comparison: white sapphire is harder than most diamond simulants but reads slightly less brilliant than diamond; view in person or via video if brilliance is a deciding factor.
• Corner protection: radiant cuts have corners that benefit from protective prong or bezel placement in daily-wear settings.
• Certification: retain the AGCL report as the primary record of treatment status.
• Ask for a personal video if you would like to see the stone in motion before finalizing the purchase.
