A natural, baroque pearl was hand-cast in metal & formed into a seamless circle, creating the perfect chunky ring. It's texture and light-refracting curves speak for themselves, but they also stack well with the Wavi Ring - Thin. 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 jewelry clean and dry using a soft cloth. Avoid wearing your jewelry 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 jewelry box or soft jewelry pouch, such as the pink branded BIKO pouch provided. Wear your BIKO jewels often, and love them always.
