How IZIOS Works
Use Diamond Scout™ to search naturally (“I want a 1.5ct oval that looks big and is under $1,500”) and get instant matches. Filter by shape, carat, color, clarity, and price. Results show measured LightScore™ evidence only where ready and keep missing scores unavailable; SmartPrice™ helps compare value. All stones ship free with insurance and can be returned within 30 days.
What Buyers Can Compare
Each product page is built around certificate-first details: lab report, stock ID, shape, carat, color, clarity, cut, polish, symmetry, fluorescence, measurements, media, and current retail price. Category pages stay clean and indexable, while filtered query URLs canonicalize back to their primary collection so search engines do not waste crawl budget on thousands of duplicate price and facet combinations.
