Every diamond on our site is GIA or IGI certified, and we display the full certificate so you can verify the 4Cs (cut, color, clarity, carat) yourself. Our pricing is transparent and competitive across the market, you're seeing the same stone other retailers list, often at a better price because we work directly with cutters and skip the showroom markup. If you'd like a second opinion, send us the certificate number via chat and we'll walk you through exactly what you're paying for.
