A shark fin–shaped specimen of druzy agate has been hand-carved to emphasize the natural eccentricities of this dazzling cut. Knotted on durable turquoise Japanese polyester for strength and longevity beyond traditional silk, the composition is punctuated with faceted black tourmaline rondelles that evoke a perpetual, summer-inflected elegance knotted at every third stone. Finished in 14k gold fill with a matching beaded extender, it balances raw mineral expression with refined, modern craftsmanship. Handmade in the United States.
