A marquise is a long oval with a point at each end. Its length makes the stone look larger than a round of the same weight, and it makes the finger look longer and slimmer. Lab-grown sapphire rates 9 on the Mohs scale, second only to diamond among gemstones, so it holds up well to daily wear. The two points are the most exposed part of the stone, which is why most designs protect them with V-shaped prongs or a bezel.
Every design can be ordered with a lab-grown blue sapphire, the classic choice, or with a lab-grown pink or yellow sapphire for a softer or brighter look. A lab-grown sapphire has the same hardness and makeup as a natural sapphire and costs far less.
Bands run from about 1.8 to 2.5 mm wide on most designs. Prices start under $300, and most rings are between about $750 and $1,050, depending on metal and style.
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.
Yes. Lab-grown sapphire is hard enough, at 9 on the Mohs scale, to be cut into a marquise with fine points at each end, and the long shape shows off its color well. Every ring in this collection sets a marquise cut lab-grown sapphire, in blue, pink or yellow. Because the points are the most exposed part, our designs hold them with prongs or a bezel to protect them in daily wear.
