when you see 585 stamped on jewelry, it’s not a size or model number — it tells you the gold’s purity. 585 means the piece is made of an alloy that contains 58.5% pure gold and 41.5% other metals such as copper, silver, or nickel.

this is the same as 14 karat gold (14k), just expressed differently: the millesimal system (parts per thousand) instead of the karat scale. sometimes you’ll see a 583 stamp instead of 585 — both mean the same thing.

 

why 585 gold is special

strength & durability:  pure gold (24k) is too soft for daily wear. by mixing it with other metals, 585 gold becomes harder and more resistant to scratches, while still keeping its warm glow.

 

affordable luxury:  585 gold balances value and quality. it’s more precious than 10k gold, but more accessible than 18k or 24k.

 

timeless beauty: depending on the mix of metals, 585 gold comes in different shades — yellow, white, or rose — making it versatile for every style.

 

colors of 585 gold

yellow gold:   mixed with copper and zinc for a classic, sunny tone.

white gold:   alloyed with nickel, silver, or palladium for a cooler, silvery finish.

rose gold:   blended with a higher amount of copper for that warm, pinkish glow.

 

💡 note: 585 gold jewelry is not the same as gold-plated or gold-filled pieces, which only have a thin outer layer of gold. when a piece is stamped 585, the gold runs throughout the entire alloy.
