About lab-grown blue sapphire

A lab-grown sapphire is corundum, the same mineral as a mined sapphire, grown in controlled conditions. It rates 9 on the Mohs scale, so it stands up to daily wear better than most colored stones. Lab-grown blue sapphires usually show even, saturated color with few visible inclusions, and they cost far less than natural sapphires of similar size and color.

Styles for a lab-grown blue sapphire oval ring

  • Solitaire and bypass: the lab-grown sapphire alone on a plain, flat or wrapping band.
  • Halo and double halo: one or two rows of lab-grown diamond accents around the blue center.
  • Pave and split shank: small lab-grown diamonds along the band, on one shank or two.
  • Three stone and side stone: lab-grown diamonds, including baguette or pear side stones on some designs, beside the oval.

Metal, carat weight and price

White gold, platinum and silver keep blue looking crisp; yellow and rose gold give it a warmer, vintage feel. Gold comes in 10K, 14K or 18K. Every design offers 1 to 9 carats total weight on the product page. Prices start under $300, and most rings are between about $750 and $1,050.
