Hultquist Copenhagen jewellery is plated with real silver and gold. The base metal is alloy and guaranteed nickel free. This base is coated with copper or palladium which gives the plating a better finish and life. All stones used on the products are selected Swarovski crystals, quartz, freshwater pearls or Czech glass beads. All are handwoven and handmade. To take care of your jewellery optimally we advise you not to spray directly with perfume or wear them during bathing or sleeping.
