Some have been sandblasted before the lustre is applied to give a matte surface, in Gold, Bronze or Metallic Black. A few bubbles have been filled with faceted, round cubic zirconia in a Champagne or Smoke colour before being sealed to add sparkle.

Please store each jewellery item separately from other items to avoid sharp surfaces which may scratch the lustre or silver. Store away from chemicals and out of sunlight. Ensure that perfume, hairspray and other chemicals are applied to the body, face and hair BEFORE jewellery is put on to help avoid the jewellery becoming dull and colours looking faded. The glass and the silver parts of the jewellery can be cleaned with jewellery cloths to remove tarnish, or the pieces can be dipped in cleaning solution, rinsed and dried. However, oxidised silver should NOT be rubbed with cloths, or dipped in chemical cleaner. Please store jewellery in airtight bags or boxes to prevent tarnishing.
