Buying guide

Why the emerald cut suits a lab-grown ruby

The emerald cut is a step cut: long, parallel facets that act like windows into the stone. On a red lab-grown ruby, that cut shows depth of color more than sparkle. A lab-grown ruby has the same chemistry as a natural ruby and rates 9 on the Mohs scale, hard enough for a ring worn every day. The cut corners help protect the stone.

Choosing the band

  • Plain band: slim, wide or flat polished metal, the simplest solitaire.
  • Pave band: small lab-grown diamonds along the shank, on most designs.
  • Bypass and twisted: bands that curve or wrap around the center.
  • Cathedral and hidden halo: a few lift the center on arches or add lab-grown diamonds under it.

Carat weight, metal and price

Every design offers 1 to 9 carats total weight. Gold comes in 10K, 14K or 18K; yellow and rose gold warm the red, and platinum or white gold sharpen it. Most bands are about 1.8 to 2.2 mm wide. Prices start under $300, and most rings are between about $750 and $1,050.
