Rings by Charlotte Verity Oxidised silver ring shank, made of 2mm round wire, with nine small handblown glass spheres. The glass is coated in red and Platinum precious metal lustres. Features Primary Material : sterling silver Other Materials : glass and precious metal lustres One of a Kind : Yes Metal : sterling silver Hallmarked : No Cleaning Instructions Lustres contain precious metals and are permanently adhered to the glass surface through high temperature firings; when the jewellery is looked after correctly it should not come off. 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. ‘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 gently rubbed with jewellery cloths to remove tarnish. If the tarnish is particularly stubborn, the pieces can be dipped in jewellery cleaning solution, rinsed and dried. Also, oxidised silver should NOT be rubbed with cloths, or dipped in chemical cleaner as this can increase the rate at which the patina fades. Please store jewellery in airtight bags or boxes to prevent tarnishing.
