Antique Style Bluish Grey Sapphire Ring 3.60 Ct., Platinum 950

This ring centers a C.Dunaigre certified cushion shape bluish grey sapphire weighing 3.60 carats, with exact dimensions of 9.40 x 8.20 x 4.98 mm. The stone is faceted in a mixed brilliant style, combining a brilliant-cut pavilion with modified crown facets to maximize return of light while preserving apparent size and color stability. The mixed brilliant configuration produces a controlled pattern of scintillation and flash, the pavilion’s numerous triangular and kite facets delivering strong brilliance, while the larger crown facets and modified corners reduce windowing and present the sapphire’s faint bluish grey saturation with evenness across the table. The gem is graded as very slightly included when evaluated at eye level, and exhibits excellent polish, attributes that together indicate careful cutting to balance visual cleanliness and optical performance without compromising structural integrity. Originated from Madagascar, this sapphire’s faint color saturation and transparent body allow for a refined, cool tone that reads bluish-grey under natural light yet remains highly versatile in matched metalwork and companion stones.

Accent diamonds are natural, white, round shaped and calibrated to provide complementary brightness without overpowering the center sapphire. The ring features groups of white round diamonds approximately 0.05 carats, 0.03 carats, and 0.018 carats respectively, all graded VS for clarity and F/G for color. These grades were selected to optimize contrast and scintillation against the bluish tone of the sapphire. The VS clarity ensures minimal internal interference to light passage at the microscopic level, preserving strong dispersion and lively brilliance in the accent stones. The F/G color grade maintains visual whiteness next to the sapphire, supporting a crisp, high-contrast appearance in both daylight and artificial illumination. The diamond placement and size graduations are engineered to create graduated brightness along the shoulders and gallery, enhancing perceived center size and maintaining a balanced visual profile from face-on and oblique viewing angles.

The mounting is fully executed in platinum 950, a material choice that prioritizes durability, long term metal stability, and hypoallergenic performance for continuous wear. Platinum 950 provides a high density and tensile strength that secures prongs and bead settings against deformation, and its ductility allows for fine, enduring detailing such as the precise milgrain beading and hand-finished engraving visible on the shank. The ring’s split-shank architecture and protective four-prong basket are engineered to stabilize the sapphire’s pavilion and crown without exposing delicate girdle regions, reducing the risk of edge chipping from incidental contact. Platinum 950’s tendency to develop an even patina with wear acts as a practical advantage, preserving structural mass around critical settings and reducing the long term need for retipping compared to softer white gold alloys. For daily wear scenarios the combination of sapphire hardness, well-placed prongs, and platinum mass creates a resilient ensemble suitable for sustained, everyday use.

Craftsmanship techniques employed in this piece reflect The Natural Sapphire Company’s emphasis on finish, fit and longevity. The mixed brilliant cutting proportions were selected to optimize depth and table relationships for the 9.40 x 8.20 x 4.98 mm cushion outline, resulting in a strong light performance while minimizing face-up darkness that can occur with deeper pavilions. The excellent polish contributes to both optical return and abrasion resistance on facet junctions, preserving the stone’s visual characteristics through years of wear. Diamond settings are executed with calibrated beads and secure prongs to hold the small round melee precisely, while the milgrain edgework is applied using traditional hand tools to produce consistent bead size and a durable rim that resists snagging. Routine maintenance recommendations include periodic prong inspections and professional cleaning to preserve optical performance and metal finish, ultrasonic cleaning is generally appropriate for both sapphire and diamond components absent undisclosed treatments, and any necessary re-polishing or retipping is straightforward given the robustness of platinum 950. This design merges technical gemology, precise faceting and enduring materials to deliver a ring perfectly suited for daily wear, sold and supported by The Natural Sapphire Company.
