Lumen is one bright light, bringing a pop of glow to the face. Featuring a unique baroque freshwater coin pearl, no two pairs are ever exactly alike. All BIKO pieces are plated in 14k gold or rhodium, over brass. They do not tarnish or cause discolouration on the skin. All earring posts are surgical stainless steel, and hypoallergenic. For increased longevity, keep jewellery clean and dry using a soft cloth. Avoid wearing your jewellery in the shower or during exercise, and wear after applying perfume or hairspray. Protect your piece from rain and humidity. When not wearing, be sure to store inside a jewellery box or soft jewellery pouch, such as the pink branded BIKO pouch provided. Wear your BIKO jewels often, and love them always. Colour: white
