Antique Style Blue Sapphire Ring 3.53 Ct., 18K Yellow Gold

This ring centers a transparent 3.53 carat marquise blue sapphire, precision cut to dimensions of 13.14 x 6.43 x 5.41 mm, with a mixed brilliant facet arrangement calibrated to balance scintillation along the length of the stone with controlled light return through the pavilion. The mixed brilliant style integrates a faceted crown pattern that maximizes fire and a pavilion protocol that preserves depth of tone, producing dynamic flashes without sacrificing the saturated core color. The sapphire exhibits vivid color saturation and an even distribution of blue, consistent with classic Ceylon material from Sri Lanka, and it has been heat treated to enhance stability and hue uniformity. Clarity was assessed as very slightly included at eye level, indicating only minor internal features that do not impede transparency or optical performance, and the cutting and excellent polish present crisp facet junctions and high symmetry. The length to width ratio of approximately 2.04 emphasizes an elegant elongated silhouette that visually lengthens the finger and allows the marquise facets to interplay with ambient light in a refined manner.

Flanking the center stone are white round natural diamonds totaling approximately 0.44 carats, set to complement the marquise geometry while reinforcing center stone contrast. Each round diamond is graded Very Slightly Included across VS1 and VS2 designations, with a color grade of F, ensuring near colorless body tone and high brilliance when paired with the vivid blue sapphire. The diamonds are hand set in an 18K yellow gold mounting that combines low profile prong work for secure girdle engagement and an open under gallery to permit maximum light access to both the sapphire and the side stones. The gold work is finished to a high polish, with refined claw prongs and a balanced crown form that showcases the marquise point integrity. As with all pieces from The Natural Sapphire Company, this ring is engineered to be both a technical showcase of gem cutting and setting proficiency and a meaningful object of memory, suitable for marking an engagement, anniversary, or other milestone. The precision of the cut, the considered matching of side stones, and the enduring warmth of 18K yellow gold create a piece intended to be worn daily and cherished for generations.
