How to keep your jewellery in
good condition:
• Rough work like
bricklaying, gardening, washing dishes etc. could harm every ring or leave deep
scratches.
• Pearls should not
be worn in saltwater or chlorinated water, but wear them frequently as our skin
enhances their lustre. Avoid shampoo, body lotion, hairspray, silver dipping
solutions etc. to come in direct contact with pearls.
• Silver dipping solutions
are not suitable for any kind of opal or pearl jewellery.
Heat, Water or other liquids can dissolve the glue in between the layers of opal doublets and triplets and make them
dull. Opals should not be exposed too long to dampness or dryness.
• Get gemstone settings checked
once a year, which we offer free of charge. Necessary repairs come cheaper than
replacing a large lost diamond.
How to clean jewellery with CLEAR
precious & other fine gemstones:
You can heat diamond jewellery in a pot well covered with water, a squirt of a mild dishwashing
liquid and cloudy ammonia added to near boiling temperature. But
watch out not to forget, as Diamonds boiled dry can end up with a black deposit, which is extremely
hard to repolish. To avoid a temperature shock, let it cool down in the water,
until you won't burn your fingers any more. Then brush well with a soft
toothbrush (no toothpaste because of abrasives in it!) Make sure the plug is in
the sink, rinse well with water and dry with a soft lint-free cloth.
C A R E should be taken with emeralds, topaz, opal, lapis lazuli, malachite and gemstones with defects, because they may not withstand higher temperatures than
about 60° C. You could always bring jewellery for cleaning or polishing to us
or another qualified goldsmith / jeweller.
