GRS-certified 5.04 carat round vivid blue Sri Lanka sapphire prong-set in an 18K white gold double diamond halo cocktail ring, featuring 32 round brilliant accent diamonds and measuring 15.7mm x 16.5mm across the face. Size 7.5, adjustable.

The 18K white gold mounting features a bold architectural double halo — an inner row of smaller round brilliant diamonds and an outer row of larger round brilliant diamonds — creating a tiered, dome-like crown that elevates the center sapphire with dramatic depth and sparkle. The four-prong center setting lifts the 5.04 carat sapphire cleanly above the halo platform, allowing light to enter the stone from all sides and maximizing the gem's vivid blue saturation. The plain tapered shank keeps the design focused entirely on the jeweled face, ensuring the sapphire and diamond halo remain the undisputed focal point from every angle.

The 5.04 carat Sri Lanka sapphire is GRS-certified as vivid blue — the highest color designation in the GRS grading system — placing this stone among the most desirable sapphires in the world by both origin and color grade. Ceylon sapphires are historically the most prized sapphire origin, known for their pure, cornflower-to-vivid blue hues with exceptional transparency and brilliance that no other origin consistently replicates. This stone carries heat treatment (H) notation per GRS, which is the accepted and standard enhancement for fine sapphires and does not diminish its value or collectibility among serious buyers. The 32 surrounding round brilliant diamonds in the double halo amplify the sapphire's blue through contrast, framing it in white fire that draws the eye immediately to the deep, commanding center gem.
