Ruby Diamond Heart Necklace 0.50tcw, 14k Yellow Gold Open Heart

The Ruby Diamond Heart Necklace from Treasured & Co. pairs the deep red of natural ruby with the icy fire of natural diamond, set into an open-heart silhouette in 14kt yellow gold. The combination is classic July-birthstone territory — and it's also the gemstone pairing most associated with passion and devotion in fine jewelry tradition.

Stone Details

The pendant carries 0.50 total carat weight, split as 0.27ct natural ruby and 0.23ct natural diamonds. The diamonds are graded H in color and SI in clarity — an eye-clean specification at this price point. Ruby is the second-hardest gemstone after diamond (Mohs 9) and exceptionally well-suited to daily wear.

Setting & Metal

The open-heart design lets light pass through the silhouette, giving the pendant a lighter visual weight than a closed-heart pavé. The heart measures 1.00" x 0.75" — a confident scale without going statement-piece. Metal is 14kt yellow gold (585 purity), and the pendant suspends from an 18-inch yellow gold chain.

Ruby — A Brief Primer

Ruby is the red variety of corundum, colored by trace chromium. The most prized rubies show a "pigeon blood" red — a vivid, slightly bluish red — and originate from Mogok in Burma. Our stone is a rich, classic ruby red, well-saturated and clean to the eye. As a July birthstone and a 15th- and 40th-anniversary gemstone, ruby carries some of the strongest sentimental associations in fine jewelry.
