2.30 Ct. Blue Sapphire and Natural Diamond Three Stone Ring, 18K White Gold

This ring centers on a transparent 2.30 carat cushion shape blue sapphire, measuring 7.70 by 6.50 by 4.78 millimeters, cut in a mixed brilliant style to maximize both brilliance and color face up. The gem exhibits vivid color intensity and an excellent polish, and it has been heat treated, a widely accepted enhancement that stabilizes and deepens the blue while maintaining the stone as a natural sapphire. Clarity is graded as very very slightly included when evaluated at eye level, which means that the sapphire appears clean to the naked eye, with only minor internal characteristics detectable under magnification. The combination of a mixed brilliant cushion cut and superior polish gives the stone lively light return and a strong face up presence, making the blue appear vivid and saturated without appearing overly dark or muted.

The origin of this sapphire is Ceylon, Sri Lanka, a provenance that greatly enhances the gem’s appeal to knowledgeable buyers. Ceylon sapphires are historically prized for their vibrant, velvety blues and a particular balance between saturation and brightness that differs from sapphires from other classic sources. The unique geology of Sri Lanka tends to produce stones with a slightly lighter tone and a clear, lively color that reads beautifully in daylight and artificial light alike. For collectors and connoisseurs, origin matters, because it speaks to the stone’s journey from mine to market, and because regional characteristics influence color, crystal habit, and typical inclusions. At The Natural Sapphire Company we document origin as part of our commitment to provenance and transparency, and this Ceylon sapphire is a fine example of why source is an important factor for educated buyers.

Flanking the center sapphire are two white asscher octagon shaped diamonds, cut with the faceted geometry and step cut proportions that complement the sapphire’s mixed brilliant cushion. The pair weighs a total of 0.61 carats, with a clarity grade of VS1, which indicates very slight inclusions that are difficult to see without magnification, and an F color grade, which is near colorless and provides a crisp, bright contrast next to the deep blue center. These asscher cut diamonds are set to enhance the sapphire without overpowering it, adding a refined, architectural accent that draws the eye inward to the vivid blue. In practical terms, the diamonds provide dazzling side light and a bright frame, while their VS1 clarity and F color ensure lasting beauty and minimal impact on durability.

The mounting is crafted in 18K white gold, chosen for its cool tone and ability to emphasize the sapphire’s blue and the diamonds’ white sparkle. This metal offers a balance of strength and elegance, suitable for daily wear and for a design that centers on a significant natural stone. From a grading and valuation perspective, the combination of a documented Ceylon origin, a well cut 2.30 carat vivid blue sapphire with very very slight inclusions at eye level, heat treatment only as the enhancement, and quality F color VS1 asscher diamonds, set in 18K white gold, creates a piece that appeals to both connoisseurs and those seeking a meaningful, well sourced engagement or statement ring. If provenance, documented quality, and classical proportions are priorities, this ring from The Natural Sapphire Company represents a thoughtful choice that combines geological significance, gemological quality, and enduring design.
