Vintage 1970s 6.47ct Oval Aquamarine 1.22ct Diamond Halo Baguette Ring Platinum

A 6.47 carat oval aquamarine of this clarity and brilliance is not a stone you encounter often. The color is the clearest, coolest blue — neither grey nor green, but purely, unapologetically aquamarine — and the material is exceptionally clean, allowing light to pass through it with a depth that photographs only partially capture.

The setting was designed to honor that stone. A full halo of fourteen round brilliant diamonds encircles the aquamarine, while four baguette-cut diamonds set into the shoulders of the band give the composition a structured, architectural quality that is distinctly 1970s platinum work at its finest. All eighteen diamonds total 1.22 carats of F/G VS quality.
