Buying guide

How a cluster ring is built

A cluster ring gathers smaller stones tightly around the center so the top reads as one larger shape. Here the lab-grown diamonds sit in floral halos, a double halo or graduated rows that step down in size from the center. The effect is a wide, bright face, with the warm yellow center standing out against the white lab-grown diamonds.

Choosing the center and metal

Round, cushion and oval centers give the most flower-like cluster. Pear, marquise and heart centers turn the cluster into a more unusual outline. Yellow gold deepens the yellow of the center, while platinum and white gold keep it crisp and make the lab-grown diamonds look whiter. Rose gold gives a softer, warmer mix.

About lab-grown yellow sapphire

A lab-grown yellow sapphire has the same chemistry, crystal structure and hardness as a natural yellow sapphire. It rates 9 on the Mohs scale, just below diamond, so it handles daily wear well. Its warm, sunny color is even from stone to stone, and it costs far less than a natural yellow sapphire of similar size.

Carat, metal and price

Every design offers 1 to 9 carats total weight. Gold comes in 10K, 14K or 18K. Prices start from about $410 at the smallest option, and most rings start at about $970 to $990.
