HPHT lab diamonds are produced under high pressure and high temperature, replicating the natural growth environment of diamonds underground. They own the same hardness, luster and optical performance as mined diamonds. Every piece is strictly inspected and graded by GIA or IGI, delivering stable and trustworthy quality. Featuring pure origin and 100% conflict-free, HPHT diamonds are priced much lower than natural ones. Available in diverse carat weights, cuts and colors, they fit rings, bracelets, earrings and various fine jewelry. Eco-friendly, durable and cost-efficient, they are widely favored for custom jewelry, daily wear, gifts and wholesale supplies.
