Three-stone Lab Grown Oval Diamond Ring
Timeless brilliance, reimagined. This three-stone oval ring features a near-flawless lab grown oval-cut center diamond, flanked by two smaller carat oval side stones for a look that’s both classic and bold. Set in 10K gold, the low-profile prong setting enhances the diamonds’ natural fire while offering a sleek, balanced silhouette. The elongated shape of the oval stone flatters the finger and maximizes surface sparkle—making it a favorite for modern brides with timeless taste or as a stunning statement ring.
