Zirconium

Zirconium in its original form is naturally grey-white, but black zirconium is trending in the jewellery industry now. The finish is achieved by putting zirconium through an oxidisation process: The zirconium is heated for several hours and it reacts with the air to create a hard, black, coating of zirconium oxide. This black finish is then polished to a high shine, or can be made into a matt finish. The polish finish will be the most black in colour – a satin/matt finish on black zirconium results in a dark gray/graphite colour. No matter what the finish, black zirconium is extremely resistant to corrosion and scratching.
