About the Item

GRS certified 5.81 carat vivid red oval cut natural ruby from Siam (Thailand). This ruby exemplifies the level of rarity and beauty we reserve for our most discerning clients. This ruby is an investment-grade gemstone, exhibiting an ideal balance of color, clarity, transparency, luster, and brilliance. It meets the highest standards in both quality and value. In rubies, the key factor is color—specifically, how red and how intense that red is. This stone is exceptionally red, with the vivid color being its most striking feature. Typically, rubies with such intense color tend to lose some transparency or become slightly cloudy. However, this gem maintains outstanding brilliance and clarity. It is loupe-clean and precisely cut in an oval brilliant shape. At 5.81 carats, the combination of these characteristics makes it an extremely rare and distinguished gemstone. Details: Item Type: Natural Ruby & Diamond Halo Ring Metal: 18K White Gold Weight: 7.05 Grams Ring Size: 6 Center Stone Details: Type: Natural Ruby Carat: 5.81 Color: Vivid Red Cut: Oval Origin: Siam (Thailand) Treatment: Heated Certification: GRS #GRS2023-095775 Side Stones Details: Type: Natural Diamond Cut: Round Brilliant Color: D-F (White) Clarity: VVS1 – VS1 (Eye-clean) Carat: 3.30 ctw (Halo), 0.12 ctw (Accent Diamonds) This unmistakably natural and noticeably valuable ring is a rare find—its vivid red ruby and white, eye-clean diamonds create a piece unlike any other.
