The Cutler and Gross x The Great Frog - Lucky Diamond II takes an anarchic vision into bolder square territory. Dagger and Lucky Diamond emblems are cast from sterling silver by a jeweller in Vicenza, while weight-saving reverse-milling and custom Lock Down Chain core wire handle the engineering. It is collaboration at the component level—Italian eyewear craft and London jewellery-making, fused frame by frame. Vicenza silverwork and Italian acetate craft meet at jewellery tolerances throughout. Handmade in Italy. Includes Cutler & Gross box, case, cleaning cloth, and 1-year manufacturer warranty.
