Product Details

Moments of love and connection feel even more special with this beautifully designed Infinity Pendant Necklace. The pendant features an 8 MM cushion cut black onyx placed at the center, held securely in prong setting to showcase its bold and smooth finish. Flanking the center stone is an infinity symbol decorated with round brilliant lab grown diamond stones, adding gentle sparkle and visual balance to the design. The contrast between the dark AAA quality black onyx and the shimmering EF-VS quality lab grown diamond creates a look that is eye-catching yet easy to wear. A hidden bail keeps the focus on the Black Onyx Pendant itself, giving the necklace a neat and polished appearance. It hangs from a classic cable chain that sits comfortably on the neckline and works well with both casual and dressy outfits. This Onyx and Diamond Necklace is thoughtfully crafted to be worn often while still feeling special. It can be styled on its own for a simple look or layered with other pieces for added charm.
