Three Stone Greenish Blue Sapphire Ring 0.77 Ct., Platinum 950

This ring centers a transparent 0.77 carat round greenish blue sapphire from Montana, with dimensions 5.52 x 5.50 x 3.57 mm, a mixed brilliant cut, very slightly included clarity as evaluated at eye level, medium color saturation, and an excellent polish. The mixed brilliant faceting combines a brilliant style pavilion with a proportioned crown that maintains strong table return while introducing additional pavilion facet facets to enhance scintillation and spectral dispersion. With an average diameter of 5.51 mm and a depth of 3.57 mm the depth ratio is approximately 64.7 percent, a proportion that favors richer face up color and contrast compared to a shallower ideal round brilliant. This deeper profile accentuates the greenish blue tone under natural and incandescent lighting, producing deeper blue green flashes and a pronounced contrast pattern, whereas a standard round brilliant with a more shallow pavilion typically maximizes face up brightness and even white light return at the expense of some color saturation.

The mounting uses platinum 950 with an open gallery and refined claw prongs to maximize light entry and stability, accompanied by white round natural diamonds weighing approximately 0.04 carats, clarity grades VS1 and VS2, and color grade F, which frame the center stone with crisp white brilliance. Compared to full round brilliant cuts the mixed brilliant center yields a livelier mix of scintillation and color depth, while compared to step cuts such as emerald or asscher it produces greater fire and dynamic sparkle rather than broad flashes. Compared to antique cushion or rose cuts the mixed brilliant delivers a more modern balance between brilliance and color retention, and the combination of excellent polish and precise pavilion geometry in this piece ensures that light is both reflected and dispersed efficiently. The result is a ring that reads as cool and refined on the finger with lively scintillation at movement, deeper tonal depth when viewed face on, and secure, high quality craftsmanship from The Natural Sapphire Company, presented in a durable platinum 950 setting to maintain the stone proportions and optical performance for daily wear.
