Solitaire Blue Aquamarine Ring 6.66 Ct., 18K White Gold

This ring centers a transparent cushion shape aquamarine, weighing 6.66 carats, with dimensions 13.07 by 10.61 by 7.89 millimeters, and a mixed brilliant cut engineered to balance scintillation and table brilliance. The pavilion depth measures approximately 60.4 percent of the length, indicating a proportion that favors strong light return while retaining the soft, watery diffusion characteristic of fine aquamarine. The mixed brilliant faceting combines a brilliant crown with modified pavilion facets, creating intense internal reflections and controlled return of blue tone, while maintaining crisp facet junctions that contribute to the excellent polish. Clarity is graded as very slightly included at eye level, meaning inclusions are minimal and do not impede transparency or the stone's window of light. Color shows light saturation, a delicate Ceylon blue consistent with Sri Lankan provenance, and the overall appearance is clean, cool and highly legible at the mounting scale. The gem was selected and finished with attention to facet symmetry and optical alignment, enhancing face up brightness and delivering a refined pale blue presence on the finger.

The setting is executed entirely in 18K white gold, employing a four corner prong basket that secures the cushion profile while leaving the pavilion open to admit light, and the shank is a slim, high polish band that emphasizes the solitaire silhouette. The construction recalls the historical intent of the famous Tiffany solitaire in its singular emphasis on maximizing light, while the four corner prong approach echoes Georgian and early Victorian corner prong techniques used to protect cushion shaped gems. The elevated basket and minimal bezel articulation are also reminiscent of mid century Cartier solitaires where an open crown and airy profile were favored to enhance brilliance. Craftsmanship from The Natural Gemstone Company focuses on hand finishing of prong tips and a precision seat for the girdle, ensuring the stone sits secure and level, and the high polish of the 18K white gold contrasts with the stone to make the pale blue color read cleaner at arm s length. This ring is presented as a study in restraint, technical proportion and historical reference, suitable for a collector who values cut geometry, optical performance and refined metal work.
