Rare GIA 1.20CT Oval Rose Cut Loose Diamond/ Engagement Ring Rose Cut Diamond History Rose cut diamonds were made popular in the Georgian Era (the 1700s), Rose cut diamonds have remerged as a popular ethereal, antique-inspired alternative to more traditional diamond cuts like brilliant cuts. They were one of the first cuts of diamonds, cut by hand to optimize sparkle in candlelight as they were made before electricity was invented. Why are they popular? Like its name, rose cut diamonds were inspired by the spiral of petals in a rose bud. Instead of a tight sparkle like a modern round brilliant cut diamond, rose cut diamonds are more known for a sensual shimmer and luster.
