The majority of Espoir pieces are crafted from premium 316L stainless steel and generously dipped over with either 18K Gold or .925 Sterling Silver for a premium, professional finish. Rhinestone and zirconia are also a staple in many of our pieces. This ensures no greening or rusting. Our costume jewelry pieces use a range of different brass and copper alloys too. We’re committed to providing premium quality jewelry at affordable price points.
