Buying guide

Why lab-grown sapphire

A lab-grown sapphire has the same chemistry and hardness as a natural sapphire: 9 on the Mohs scale, second only to diamond, so it holds up well to daily wear in an engagement ring. Lab-grown sapphire is usually cleaner and more evenly colored than a natural sapphire of the same size, and it costs less. Blue is the classic choice; pink and yellow lab-grown sapphire look bright and warm against yellow gold.

Choosing the band

  • Plain band: keeps all attention on the lab-grown sapphire. Wide flat and double claw versions give a bolder look.
  • Pave band: lab-grown diamond accents along the shoulders add sparkle without a halo; some designs graduate the stones toward the center.
  • Split shank, bypass and twisted: the band divides, wraps or turns as it meets the center, for more shape on the hand.
  • Hidden halo: a row of lab-grown diamonds under the center, seen from the side.

Many designs also let you pick the band width, from about 1.8 to 2.5 mm.

Carat weight and price
