{"product_id":"1-13-ct-radiant-white-sapphire-colorless-untreated","title":"1.13 ct Natural Unheated White Sapphire – Radiant Cut | AGCL Certified | Sri Lanka (Ceylon)","description":"\u003cp\u003eA 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.\u003c\/p\u003e\u003cdiv style=\"border: 2px solid #5b2c6f; border-radius: 10px; padding: 20px 24px; margin: 28px 0; background-color: #f9f5fc;\"\u003e\n\u003ch2 style=\"margin-top: 0; margin-bottom: 12px; color: #4a235a;\"\u003eExpert Opinion\u003c\/h2\u003e\n\u003cp style=\"font-weight: 600; margin-bottom: 6px;\"\u003e\u003ca href=\"\/ar-hk\/pages\/ahmed-shareek-about-the-owner\" style=\"color: #4a235a; text-decoration: underline;\"\u003eAhmed Shareek\u003c\/a\u003e's Assessment\u003c\/p\u003e\n\u003cp style=\"font-style: italic; margin-bottom: 0;\"\u003e\"At 1.13 ct, this radiant-cut white sapphire is sized to carry as a genuine engagement-ring center stone rather than an accent — and the radiant cut gives it noticeably more brilliance than a step-cut shape in this same color.
