The Kate rivière necklace makes a striking comeback as an everyday staple. What was once reserved for special moments, the single-strand lab-grown white sapphire necklace is reimagined with individually set white sapphire gemstones and a custom clasp to elevate your every look. Even the most discerning jewelry eye will do a double take. She was carefully designed with a fine jewelry design and custom clasp. I believe I purchased the 15 inch; however, I do show the measurements in the photos. The receipt or my profile does not say the specific size. This necklace is only worn for special occasions and is in perfect condition.
