Here are a few tips that your customers may find helpful to keep their Jewellery looking bright and sparkling.
Advise your Clients to always protect their jewellery from sharp blows, scratching, chemicals, sunlight and heat/cold. Ideally, they should store their jewellery in a soft lined box or pouch, and kept apart so that they don't rub together or tangle up.
Gemstones vary in hardness and are susceptible to scratching and breaking. Gemstones need to be treated with the love and care they deserve.
Gemstone hardness is based on a standard called the Mohs scale. The higher the Mohs scale number, the harder the stone is. Quartz (the stone that makes up sand) is rated at 7 on the Mohs scale, and that is why any gemstone with a rating of less than 7 is easily scratched (such as coral, lapis lazuli, opal, pearl, and turquoise
The Mohs Scale (examples)
Ruby, Sapphire 9
Spinel, Topaz 8
Aquamarine, Emerald 7-8
Amethyst, Chalcedony, Quartz, 7
Steel (pocket knife) 7
Lapis lazuli 5-5.5
Bronze, Coral, Pearl 3
Silver, Gold 2-3
Amber, Fingernail, Ivory, Shell, Jet 2.5
Also, some stones can be quite porous (such as opal, pearl, turquoise), these kind of stones immersed in water for too long.
Some gemstones can be affected by exposure to sunlight. It is wise not to display or store stones susceptible to fading in direct sunlight.
Some popular stones that are affected include:
Silver is a fine, precious metal. Its colour is silver-white and it is often used in jewellery. Silver has to be alloyed (mixed) with other metals in order to use in jewellery production. This mixing of metals makes it more durable and rigid.
Jewellery and Silverware are traditionally made from Sterling Silver (standard silver), an alloy of 92.5% silver with 7.5% copper.
Under normal conditions, Silver will tarnish - it's the mixture of moisture and sulphur in the air we breathe that causes Silver to tarnish.
