Art Deco 2 Carat Princess & Round Diamond Channel Sapphire Platinum Ring

Platinum Art Deco 1930s Channel Cut Sapphire and Princess Cut & Round Brilliant Diamonds Platinum Ring ; Diamond Princess Cut/Round Cut=~2 CTW, PT-7.1g (9x23mm ring) size 7.5

An Art Deco circa 1930s platinum wide band cocktail ring featuring a center panel of four invisibly set princess cut diamonds flanked by channel-set square blue sapphires top and bottom, bordered by two vertical rows of round brilliant diamonds, with square sapphire shoulder panels on each side, totaling approximately 2.0 carats of diamonds.

Ring Size 7.5, adjustable; ring face measures 9 x 23mm; 7.1 grams.

The ring face is composed in a strictly geometric three-zone layout that is unmistakably Art Deco in its design language — a central vertical panel of four princess cut diamonds flanked above and below by rows of channel-set square blue sapphires, all framed on left and right by twin vertical columns of round brilliant diamonds in individual settings. The shoulders extend the composition with large square blocks of channel-set blue sapphires that step down dramatically toward the tapered platinum shank, creating a wide 23mm face that commands the hand with the bold, architectural presence characteristic of the finest 1930s platinum jewelry. Every element — the geometric segmentation, the strict horizontal and vertical lines, the high-contrast alternation of white diamond and deep blue sapphire — reflects the Art Deco design philosophy at its most disciplined and refined.

The approximately 2.0 carats of diamonds span two distinct cut styles that create deliberate visual contrast — the princess cut center cluster delivers broad, clean geometric light flashes consistent with the Art Deco preference for precise, faceted brilliance, while the round brilliant flanking rows provide the continuous scintillation and fire that animate the border of the face. The square channel-set blue sapphires are deep royal blue with strong saturation that reads as near-black in certain lights and vivid blue in others — precisely the dramatic, high-contrast color pairing that Art Deco jewelers favored when combining sapphire with platinum and diamond. The platinum mounting has developed the natural patina of a 90-year-old piece, with the characteristic soft silver-grey tone that distinguishes genuine period platinum from modern reproductions.
