A 1.5 carat lab grown diamond typically costs between $1,500 and $4,000 depending on quality factors.
Lab grown diamonds offer a more affordable alternative to natural diamonds while maintaining identical physical and chemical properties. The price of a 1.5 carat lab grown diamond varies based on the 4Cs: cut, color, clarity, and carat weight. These diamonds are created in controlled laboratory environments using either High Pressure High Temperature (HPHT) or Chemical Vapor Deposition (CVD) methods, resulting in gems that are visually and structurally identical to mined diamonds.
