Art Deco Sapphire and Diamond Stickpin of Platinum and 18k Gold

An elegant creation from the Art Deco era (circa 1920), this antique stickpin features a geometric square design set with deep blue sapphires and sparkling diamonds in platinum, perfectly capturing the era’s fascination with symmetry, contrast, and refined luxury. The composition is supported by a slender 18k gold stem, a hallmark of fine craftsmanship from the early 20th century.

The pin head measures approximately 0.3 inches high by 0.4 inches wide, with an overall length of 2.8 inches. Its clean lines and striking color pairing make it a versatile jewel—equally suited for a lapel, tie, or coat.

The metal content has been professionally verified using XRF (X-ray fluorescence) analysis and confirmed with traditional jeweler’s acid testing, authenticating their platinum and 18k gold composition. In excellent antique condition, this piece embodies the precision, glamour, and understated sophistication that define true Art Deco design.
