Rose Cut Diamonds
Cut description and origin
Rose cut diamonds date back to the 1500's, and were still commonly in use during the early 18th through to the early 20th centuries throughout Europe. They feature a flat bottom with a faceted, dome-shaped top and are named for their shape, which resembles a rose bud. This style of cutting produces a much clearer, transparent stone in comparison to a brilliant cut diamond, with a softer, muted sparkle.
These diamonds are graded in line with modern brilliant cut diamond standards, however this excludes a cut grade.
Traditionally rose cut diamonds were cut from white material, but in recent years they have been cut in a wide variety of colours. Many salt & pepper and grey diamonds are cut in this shape since they don't require the faceting of a brilliant cut diamond as they don't produce the same sparkle.
Most rose cut diamonds are sold uncertified, though exceptional stones can be accompanied by GIA certificates in rare situations.
The value of a rose cut diamond matches that of its brilliant cut alternative and is dependent on quality factors such as colour, clarity and carat. If the stone is accompanied by a certificate it is generally valued higher than an uncertified stone of the same qualities.
