Yellow gold is a precious metal that DFLY strives to use exclusively recycled. The great civilizations have used it for millennia for adornment. This noble metal with bright reflections is remarkably malleable and ductile, it is easy to work with. Its flexible material mixed with copper and silver renders it more resistant. DFLY only uses an alloy with a very high gold content: 18K, corresponding to 750 grams of gold per 1000 grams of material.
