Antique Style Bi Color Sapphire Ring 0.64 Ct., 18K White Gold

This ring centers a 0.64 carat round bi color sapphire, measuring 5.62 x 5.42 x 2.98 mm, cut in a mixed brilliant style to balance color zoning and scintillation. The mixed brilliant cut combines a brilliant facet arrangement on the crown with a more controlled pavilion geometry, directing light through the color zones to enhance both hue and sparkle. Medium intense color saturation is preserved by the cutter through careful pavilion angles, allowing the blue and yellow tones of this Ceylon sapphire to remain distinct without one overpowering the other. The stone carries a clarity description of very slightly included evaluated at eye level, and the excellent polish ensures facet junctions remain sharp, which minimizes light leakage and maximizes contrast between flash and body color. The sapphire has been heat treated, a stable and widely accepted enhancement, implemented to improve tone and uniformity while retaining the natural bi color character typical of Sri Lankan material.

The setting, executed entirely in 14K white gold, is engineered to accentuate the gem's clarity and dual hues. A raised crown with an open gallery and discrete prong placement allows unobstructed light entry to the pavilion and permits light to exit through the crown, increasing the perceived brilliance of the mixed brilliant cut. The white gold acts as a neutral reflector, reducing warm metal interference that could mute the cooler blue component of the bicolor effect, while its high polish provides micro reflections that frame the stone and emphasize its faceted geometry. Fine filigree and openwork beneath the bezel serve both aesthetic and optical functions, creating controlled shadowing that deepens the saturation at the stone perimeter, enhancing the visual separation between the two colors. Precision prong tips are shaped to secure the crown while exposing maximum table area, facilitating inspection of the very slightly included clarity grade without unnecessary metal obstruction. As presented by The Natural Sapphire Company, this ring is a study in how cut, clarity, and setting interact, with the mixed brilliant cut and 14K white gold mounting working in concert to present the sapphire at optimal color balance and luminous performance.
