Accent Stones Bi Color Sapphire Ring 1.31 Ct., Platinum 950

This ring centers a transparent 1.31 carat cushion shape bi color sapphire, precisely measured at 6.15 x 5.50 x 4.22 mm, cut in a mixed brilliant style to balance color saturation and optical performance, and set in platinum 950 for structural integrity and visual neutrality. The mixed brilliant cut incorporates brilliant style crown faceting to generate concentrated scintillation and a modified pavilion geometry that preserves and deepens the stone s inherent color, a critical decision when working with bi color material from Ceylon Sri Lanka. The cutter has emphasized pavilion depth and table proportion to maximize internal reflection without sacrificing face up size, resulting in intense color saturation and an excellent polish that accentuates the sapphire s violet blue and cornflower tone transition. Heat treatment has been applied to stabilize and intensify color, a well understood and widely accepted enhancement in Ceylon sapphires, and the clarity is graded very slightly included when evaluated at eye level, meaning the stone is effectively eye clean with minor internal features that do not detract from brilliance or color when viewed in typical lighting.

The setting architecture has been developed to enhance both color and perceived clarity by optimizing light delivery and return. The center sapphire is held in a four prong crown that secures the girdle while allowing open pavilion exposure, enabling light to enter through the crown and pavilion and to reflect back through the table which strengthens the stone s vivid hue and enhances contrast. The prongs are slender yet robust, polished to a mirror finish to minimize visual obstruction and to reduce light absorption at the girdle, so the sapphire reads larger and cleaner face up. An open undergallery permits unobstructed light flow beneath the pavilion, a key element in amplifying the mixed brilliant cut s internal reflections and in reducing the visual impact of any small inclusions by increasing scintillation wash across the table. The platinum 950 mounting provides a cool white metal contrast that does not impart warm overtones to the sapphire, therefore preserving the sapphire s native bi color expression, while the metal s higher density and ductility allow for finer, more secure prong tips and a low profile seat that centers the optical axis of the stone for optimal face up symmetry.

Flanking the center stone are white round shaped lab grown diamonds, approximately 0.03 carats and 0.02 carats, clarity Very Slightly Included, VS1, VS2, and color grade F, selected to deliver bright white light return without overpowering the sapphire. These melee diamonds are positioned in precise prong settings along the shoulders, calibrated in size and angle to act as optical mirrors that bounce white light into the sapphire s lower facets, increasing perceived brightness and delineating the center stone s outline. The VS clarity range ensures that the accent stones present clean facet junctions under loupe inspection, while the F color grade guarantees a cool white contrast with the platinum that complements the sapphire s cooler color axis. All diamond seats and prong profiles are finished to a high polish to avoid shadow lines and to maintain maximum refraction, and the transition from gallery to shank is hand finished to ensure consistent metal thickness, comfortable wear, and long term durability.

The Natural Sapphire Company s execution brings gemological knowledge together with exacting craftsmanship to create a ring where cutting decisions and setting geometry are coordinated to elevate color and clarity. By pairing a finely cut cushion mixed brilliant sapphire of Ceylon origin with carefully matched lab grown diamonds and a platinum 950 setting, the design maximizes light performance, preserves the stone s bi color character, and minimizes the visibility of minimal inclusions. The result is a technically thoughtful piece that reads as both lively and refined in hand, a ring that demonstrates how considered faceting and meticulous metalwork work in concert to reveal the fullest optical potential of exceptional natural sapphire material.
