Buying guide

Choosing a lab-grown sapphire color

  • Lab-grown blue sapphire is the classic choice, and the white halo makes the blue look deeper.
  • Lab-grown pink sapphire reads soft and warm, and pairs well with rose gold.
  • Lab-grown yellow sapphire gives a bright, sunny center that looks richest in yellow gold.

All three rate 9 on the Mohs scale, so they hold up well to daily wear.

Single halo, double halo and band styles

A single halo frames the center with one ring of lab-grown diamonds and makes it look larger. A double halo adds a second ring for more sparkle. Most designs carry pave down the band, others use a split shank or crossover band, and a plain band keeps the look simple. Some designs add vintage milgrain, filigree or floral details.

Total weight, metal and price

Every design offers 1 to 9 carats total weight, chosen on the product page. Gold comes in 10K, 14K or 18K, and every design is also made in platinum and silver. Prices start just over $300, and most rings are between about $800 and $1,000 at the smallest option.
