About the Item

Merkaba Jewelry Beverly Hills presents a rare, collector caliber 9.91 carat unheated Star Ruby ring, prized for its beautifully defined asterism that appears as light moves across the surface of the gem. Cut as a classic cabochon to showcase the star effect at its finest, this ruby offers an unmistakable presence and a heritage level look that connoisseurs immediately recognize. Handcrafted in platinum, the centerpiece is framed by 48 round brilliant diamonds totaling 1.71 carats, creating a luminous halo that intensifies the ruby’s depth and highlights the star phenomenon with striking contrast. The top of the ring measures approximately 0.85 inches in length, giving the piece a bold, high jewelry silhouette while remaining refined and wearable. Unheated rubies are highly sought after because they retain their natural color without enhancement. As the July birthstone and the traditional 40th anniversary gemstone, ruby carries enduring symbolism of love, protection, vitality, and devotion, making this ring an exceptional choice for a milestone gift or a cornerstone acquisition for a serious gemstone collection. A GIA certificate accompanies the ring to confirm authenticity and quality. The ring is currently size 10, and complimentary resizing is available upon request.
