Buying guide

Three ways to build a cluster

The collection holds a floral double halo, where two rows of lab-grown diamonds ring the lab-grown sapphire like petals; a star-shaped floral halo on a pave band; and a graduated cluster, where lab-grown diamonds step down in size beside the center and an open basket lets light in below. The halos give the most coverage and make a modest lab-grown sapphire look larger. The graduated style shows more of the stone's own outline.

Lab-grown sapphire in blue, pink or yellow

Blue is the classic choice and contrasts strongly with yellow gold. Pink reads softer and blends with the warm metal, and lab-grown yellow sapphire gives a sunny, almost monochrome ring. All three are lab-grown corundum, the same mineral as natural sapphire, and rate 9 on the Mohs scale, so they hold up to daily wear. Every design offers 1 to 9 carats total weight.

Picking a karat of yellow gold

Every ring comes in 10K, 14K or 18K yellow gold. 10K is the hardest and palest of the three, 18K has the deepest yellow and is a little softer, and 14K sits between them. Prices start at about $975 for the smallest option, and most rings sit near $1,000.
