Silver: an alloy of 92.5% fine silver, and 7.5% copper
24k
Gold = 99.9% pure gold
22K
Gold = 90% gold, 10% silver and/or copper
18K
Gold = 75% gold, 25% silver, copper, and/or zinc

White
gold, rose gold, green gold, or other colors of gold
are composed of 24K gold and other metals, which change the
color of the gold from yellow. Because enough enough copper,
palladium, or nickel is needed to achieve a color change,
these alloys are always 18K or lower.
Mokume
Gane: A laminate technique composed of fused sheets
of varying alloys that are hammered, carve, and/or filed to
expose a cross section, creating unique patterns. This technique
is similar to damascene steel.
I
repoussé sheets of unpatterned, straight grain mokume
and grind the surface afterwards to reveal the resulting cross
section of metals.
