The Constance Ring — Lab-Grown Oval Diamond Ring in 14k Yellow Gold with Emerald and Sapphire Crown Detail A 2.25 carat lab-grown oval diamond (E, VS1), bezel set in 14k yellow gold with a fluid, sweeping silhouette that feels as though the gold grew around it naturally. Seven round emerald and sapphire stones rest in a burnish setting along the crown — a hidden garden, discovered only up close. The Constance Ring by By Shanira is jewelry with a secret. From a distance, it reads as effortlessly modern — all sweep and light and quiet gold. But lean in, and there they are: natural emeralds and sapphires nestled at the crown like something placed there intentionally, intimately. A ring that reveals itself slowly, and stays with you long after.
