This necklace is made from hypoallergenic brass plated in gold alloy, coated with a mattifying top coat to give it a brushed look. It is free from lead, nickel, cadmium and other materials that will irritate the crap outta your skin. Yay. Avoid contact with excess moisture and chemicals when possible- soap, perfume, saltwater, sunblock, tanning oil, sweat etc. might affect the finish.
This necklace style is a fine curb chain with a gold plated spike charm. The chain measures 20” end to end including the clasp.
