About the Item

Certified Thai Natural Ruby 5.91 Carat Diamond Ring Art Deco Style 18K White Gold AIGS A breathtaking and highly important natural Thai ruby and diamond statement ring featuring a magnificent 5.91 carat octagonal step-cut (emerald cut style) ruby, dramatically elevated in a bold Art Deco inspired architectural mounting crafted in solid 18K white gold. The center gemstone displays a vivid pigeon blood red appearance to the eye, with beautiful internal life, glow, and saturation that commands immediate attention on the hand. The ruby is flanked by finely matched vertical baguette-cut and round brilliant-cut diamonds totaling approximately 0.83 carats, graded F color and VS clarity, creating strong symmetry, brilliance, and refined high-jewelry presence. The geometric side diamond arrangement enhances the prominence of the center stone while delivering exceptional finger coverage and a powerful collector aesthetic. Importantly, the ruby is accompanied by an identification certificate from AIGS (Asian Institute of Gemological Sciences) — a highly respected gemological laboratory whose reports are widely accepted by major international auction houses and the global colored gemstone trade. This provides confidence in the stone’s authenticity, treatment disclosure, and gemological integrity. The ruby has undergone traditional heat treatment, the most accepted and historically established enhancement for rubies and sapphires. Heat treatment improves transparency and intensifies color without introducing foreign substances. In fact, well over 90% of rubies on the international market — including those sold at Sotheby’s and Christie’s — are heat treated, and stones with strong color after heating remain highly desirable and valuable. Thai rubies hold long-standing importance in the world of fine jewelry. Thailand has historically been one of the most influential centers for ruby cutting and trading, producing gemstones known for their deep, dramatic red tones, strong brilliance, and classic luxury appeal. Stones from this region have been used in both vintage high jewelry and contemporary statement designs for decades. The ring’s bold Art Deco inspired silhouette, combined with the scale of the ruby and the crisp diamond geometry, creates a timeless yet modern luxury jewel. This exceptional piece would make a spectacular ruby engagement ring, cocktail ring, or centerpiece in a serious colored gemstone collection. A powerful combination of size, color presence, certification, and refined craftsmanship, this ring represents an outstanding opportunity to acquire a striking natural ruby jewel with enduring collector relevance. 5.91 Carat Natural Thai Ruby Diamond Ring Art Deco Style 18K White Gold AIGS Metal: 18k White Gold 750 Stone Weight: 5.91 ct Thai-Ruby Diamond Weight: .83 ct
