Hot Diamonds HD X JJ Calm Pearl Signet Ring Before I started working on the design of this collection with Hot Diamonds, I didn’t wear too many gemstones as I preferred a simple gold finish. Now, I have completely changed my mind, and I think breaking up the gold with a splash of natural gemstone creates a stunning overall look, and you seem to agree as our Pearl and Malachite designs are amongst your most-loved! This jewel is crafted from genuine Mother of Pearl, 925 sterling silver, a real hand-set diamond and 18ct gold plate. You need it in your life! This pearl section of this ring measures 11mm in width. Metal Type: Silver
