Mysterious yet strikingly beautiful - pearls are a beacon of light from the water's depths. The Molten Collar was created from a genuine flameball pearl that was first hand-cast, then hollowed out and made into seamless connecting forms that are lightweight for wearability. Each component is hand-polished to a mirror finish, and then plated in 14k gold. The Molten Collar sits comfortably on the neck, exuding feelings of beauty, brightness and contentment. She's one very special and timeless piece you'll love for years to come. 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.
