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.
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.
Each ring is made for you in 10–15 days. Shipping is free on orders over $500, returns are accepted within 30 days, and one resize is free within 60 days of delivery.
