Buying guide

What a cluster ring looks like

A cluster ring groups several stones tightly so they read as one larger shape. Here the cluster takes a few forms: a floral double halo that wraps the lab-grown ruby in two rows of lab-grown diamonds, a star-shaped floral halo above a pave band, and a graduated cluster of lab-grown diamonds that step down in size beside the lab-grown ruby, with an open basket underneath. A halo makes the center look wider, while the graduated look leaves more of the lab-grown ruby's outline in view.

Size and shape of the lab-grown ruby

Every design offers 1 to 9 carats total weight, so you can keep the ring delicate or let the red take over the hand. Round and oval lab-grown rubies suit a flower-like cluster best. Pear, marquise and emerald shapes stretch the look along the finger, and a heart reads as a romantic choice. A lab-grown ruby is the same mineral as a natural ruby, corundum, and rates 9 on the Mohs scale, so it handles daily wear well.

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. Yellow gold warms the red of the lab-grown ruby and makes the white sparkle of the accents stand out. Prices start at about $975 for the smallest option, and most rings sit near $1,000.
