About this product

Macy's Lab-Grown Ruby Tennis Necklace features square-cut lab-grown rubies set in a gold-plated sterling silver chain with an 18-inch length and box lock clasp. This all-around design showcases a total of 48.5 carats in gemstone weight, offering a radiant appearance similar to natural rubies. The lab-grown stones are chemically, physically, and optically identical to mined gems, created through controlled processes that mimic natural formation. The necklace is suitable for everyday wear but requires special care due to the nature of gemstones. It comes with complimentary in-store cleaning at participating locations.
