What Makes Our Round Lab-Grown Diamonds Unique
One Timeless Shape, Endless Jewelry Possibilities
From bridal jewelry to everyday fine jewelry and luxury accessories, our round lab-grown diamonds offer jewelry
brands a versatile stone shape for developing collections across different styles, settings, and price points.
For those seeking a lasting symbol of love and commitment, the round diamond remains a timeless favorite, with popular setting designs: solitaire, halo, and pavé.
A single round diamond makes a simple, elegant pendant, while halo settings and multi-stone arrangements create a more eye-catching look.
They're a popular choice for classic studs, halo earrings, and diamond hoops. With different carat weights and clarity grades, our products offer flexibility across styles and price points.
The round shape lends itself to the repeated settings of tennis bracelets and pavé bangles, creating an even, continuous line of sparkle.
Round lab-grown diamonds add sparkle to watch bezels, dial markers, and bracelets. They also feature in brooches, cufflinks, tie clips, and jeweled hair accessories.
