Shop by Lab-Grown Diamond Shape

Lab-grown diamonds offer the same optical and physical properties as mined diamonds, with ethical sourcing and better value. The shape you choose changes how your lab-grown diamond catches light. Round cuts give maximum sparkle. They have been the standard for over a century. Oval shapes make fingers look longer and show good fire. Cushion cuts have rounded corners and a soft look. Emerald and Asscher cuts use step facets instead of brilliant facets. They show clarity over sparkle. Princess cuts are square with sharp corners. Radiant cuts combine the emerald shape with brilliant faceting. Pear, Marquise, and Heart shapes suit those who want something less common. All shapes come in white gold, yellow gold, rose gold, or platinum.

Lab-Grown Diamond Setting Styles

Each setting style showcases your lab-grown diamond differently. The setting affects how light enters the stone and how secure it sits. Solitaire settings showcase a single stone with timeless elegance. Three stone designs symbolize past, present, and future. Bezel settings wrap the stone in metal for a secure, modern look. East west settings turn the stone horizontally for a unique perspective. Halo settings surround the center stone with smaller diamonds for maximum sparkle. Hidden halo designs tuck diamonds beneath the crown for subtle shimmer from the side. Pave bands feature small diamonds set along the band for continuous sparkle.
