Three Stone Blue Sapphire Ring 4.23 Ct., Platinum 950

Presented by The Natural Sapphire Company, this ring is a study in rarity and refined restraint, centered on a GIA certified Blue sapphire of truly distinguished presence. Weighing 4.23 carat, this asscher octagon shaped gem measures 8.47 x 8.31 x 6.15 mm, and displays a vivid color saturation that is both deep and lucid. The asscher cut emphasizes geometry and light, offering an arresting combination of step facets and a broad table that draws the eye into the stone and reveals an inner depth that is uncommon in sapphires of this size. The clarity has been evaluated as very slightly included at eye level, a characteristic that testifies to the natural origin and individuality of the gem, and the polish has been rated excellent, ensuring a surface finish that maximizes brilliance and contrast. Mined in Madagascar and accompanied by GIA certification, this sapphire is not merely a center stone, it is a rare find reserved for those who appreciate provenance and the quiet assurance that comes with rigorous gemstone grading.

Complementing the central sapphire are white trillion shaped natural diamonds, with a combined weight of approximately 0.50 carats, clarity grades of Very Slightly Included in VS1 and VS2, and a color grade of F. The trillion cut side stones have been selected for symmetry and scintillation, positioned to enhance the asscher form while contributing a crisp white contrast that heightens the sapphire blue. The triangular profile of the trillions frames the center gem with modern elegance, offering facets that catch and return light in lively flashes, while their matched clarity and color maintain a harmonious balance across the ensemble. Every diamond has been chosen for its ability to complement the vivid saturation and step facets of the asscher cut, resulting in a ring that reads as a single composed work rather than a collection of disparate parts.

The entire mounting is executed in platinum 950, a noble metal chosen for its strength and enduring color, and the setting has been engineered with security and longevity as paramount considerations, providing peace of mind to the wearer. The sapphire is held in a robust four prong configuration with each prong precisely formed to cradle the octagonal corners, and the prongs are integrated with a reinforced gallery and a low profile basket that secures the pavilion while allowing light to enter freely from below. The trillion diamonds are set in secure three prong seats, with careful machining and hand finishing to ensure the claws are polished and rounded to prevent catching. Platinum 950 offers exceptional malleability for exacting setting work, and its high density reduces the risk of deformation, making it the ideal metal to protect a stone of this caliber. Our bench jewelers perform multiple inspections, including tactile checks and magnified evaluations at every stage of assembly, so the finished ring leaves our workshop with structural integrity that matches its aesthetic refinement.

Ownership of this ring is an invitation into a select perspective on fine gemstones, a chance to bear a piece that is both demonstrably authenticated and personally significant. The Natural Sapphire Company stands behind the provenance and technical specification of this piece, and we provide the original GIA report with every sale, together with professional advice on care and an option for insured delivery and discreet packaging to suit individual preferences.
