Selecting silver jewellery
Selecting silver jewellery is consistent and time effective. It is only a means of re-production. Casting of silver predominately consists of molding the metal into various shapes and sizes. The pendants, necklaces, bangles, bracelets, puja thali, anklets and earrings that are currently designed in silver are remarkably similar to those that have been made centuries ago.
The designs exhibit rarest patterns made in the industry. This antique jewellery is made from all types of silver including pure silver, German silver and sterling silver. Casting or founding is shaping of metal by melting and pouring into a mold. Exotic and timeless, antique silver jewellery are now high fashion and are suddenly very chic collectible to wear.
How Durable is My Gemstone Jewellery?
First of all a note about the hardness and therefore relative durability of gemstones. To measure hardness, the jewellery industry uses the Mohs scale. This gem-trade standard, conceived by Friedrich Mohs in 1812, measures the ability of a gem or mineral to resist abrasion damage.
Diamond at 10 is the hardest whereas talc at 1 is the softest. Popular gemstones like amethyst and citrine register 7 whereas rubies and sapphires register 9. Most of us come off the beach on the first day with the 3 sís all achieved - rings caked in sand, sea-salt and suntan lotion. Nude sunbathing, as far as silver and gold jewellery is concerned, is a must! Remember also that sand will scratch the surface of precious metals.
Gems are silicates which can be very stable, hard minerals. Like gemstones, one of the characteristics of a precious metal is its rarity. A few gems are oxides and only one gem, diamond, is composed of a single element, carbon. Often, new names will be created for ordinary sounding minerals which sound prettier or more valuable, such as Moldavite for the green variety of tektites.
It could not be "precious" if it were common! This means that the metal must be malleable, that it can be bent, hammered, or otherwise shaped. Two other characteristics are also important. There are also many gemstones that are not true minerals, but which are gemstone varieties of recognized minerals.
