Precious Metals
18k Yellow Gold
Refined — Switzerland (LBMA certified)
About
Gold at 18 karats is 75% pure gold alloyed with copper and silver for durability. We work exclusively with LBMA-certified refiners and require full chain-of-custody documentation from mine to workshop. Our alloying ratios are proprietary — we develop the specific warmth and workability profile for each commission with the goldsmith. 18k is the standard of fine jewelry because it balances purity with structural integrity across a lifetime of use.
