Art Deco Unheated Ceylon Sapphire and Diamond Brooch in Platinum

Architectural Geometry Illuminated by Rich Blue Sapphires and Diamonds Bold geometry and exceptional color come together in this striking Art Deco sapphire and diamond brooch, beautifully crafted in platinum. The compact composition is arranged as a series of interlocking horizontal, vertical and curved forms, reflecting the Art Deco period’s fascination with symmetry and architectural design. Square and rectangular step-cut unheated Ceylon sapphires form the brooch’s strong geometric framework, displaying deep blue color with flashes of vivid brilliance as the piece moves in the light. Curved platinum sections set with round diamonds soften the linear arrangement while creating a bright contrast against the saturated blue sapphires. An additional round diamond set within a square platinum frame anchors the base of the composition, completing the brooch with a final point of light. The cool white tone of the platinum setting enhances the whiteness of the diamonds and allows the blue sapphires to remain the visual focus. Open spaces incorporated into the center of the design give the brooch depth and lightness while emphasizing its precise, architectural character. Measuring approximately 1 inch by 0.7 inch, this is an intimate jewel with a remarkably strong visual presence. Its compact proportions make it suitable for wearing on a lapel, collar, scarf or evening ensemble, either alone or as part of a curated grouping of Art Deco brooches.
