Why James Allen Leads Online Diamond Retail
James Allen pioneered 360° HD diamond video in 2010 — and the entire industry has been trying to catch up ever since. Their proprietary imaging technology photographs every diamond in their inventory with close-up video that lets you inspect a stone's cut quality, inclusions, and brilliance as clearly as you could in person. For a purchase as significant as a diamond, that level of transparency is everything.
360° HD Diamond View
Every diamond — natural and lab-grown — comes with a high-definition 360° video. You can see exactly how light plays through the facets, identify inclusions, and verify cut quality before committing.
GIA & IGI Certified Only
Natural diamonds carry GIA certificates, the industry gold standard. Lab-grown diamonds carry IGI certificates. Every stone is independently graded — you get a permanent record of exactly what you're buying.
