The marquise is an elongated shape with two pointed ends. It makes the stone look larger for its weight and makes fingers look longer. In a marquise cut lab-grown blue sapphire ring, the long outline shows a deep, even blue along its length. Lab-grown blue sapphire is the same mineral as natural sapphire and rates 9 on the Mohs scale, so it suits a ring worn every day. The points are the most exposed part, so many designs hold them with V-shaped prongs.
Every design offers 1 to 9 carats total weight. White gold, platinum and silver keep the blue looking cool and bright, while yellow and rose gold give it a warmer, vintage feel. Gold comes in 10K, 14K or 18K. Prices start under $300, and most rings fall 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.
