Beautiful thick aluminum bar is stamped with a single heart to create this trendy yet timeless necklace. The bar is made of solid aluminum (super lightweight and silver in color) and is hand stamped and finished with hammered texture along outside of the bar. Aluminum is an affordable alternative to sterling silver... it's pure aluminum, hypoallergenic, and has less of a reaction to sensitive skin than sterling silver! Chain is solid sterling silver, dainty and shimmery but very durable, each link is individually soldered closed. Proudly made in the USA!!!
