Features Primary Material : sterling silver Other Materials : blown glass and faceted round stones One of a Kind : No Metal : sterling silver Hallmarked : No Cleaning Instructions Please store each jewellery item separately from other items to avoid sharp surfaces which may scratch the 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. ‘Oxidation’ is a process whereby the silver is treated to produce a dark patina on the surface. It is semi-permanent and may gradually wear off. Earrings, brooches and items that remain static and do not often come into contact with skin can retain their patina as long as they are cared for, whereas oxidation on rings and bracelets, for example, is prone to fading. 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.
