General Care of ornametns
Each piece of jewellery is very delicate so we must have to take care of them. So treat your jewellery with loving care and respect. It will stay young looking like most women. Remember to put your jewellery on after applying make-up and the hairspray and avoid contact with perfume.
Before entering a chlorinated pool remove all ornaments. Remove your jewellery when carrying out cleaning or other chores. Remove all jewellery if you’re contemplating a sauna as it will burn you when it heats up. Cleaning fluids can damage both the metal and the gemstones. Many gemstones are damaged by prolonged exposure to heat. A miss-hit with the hammer could end a beautiful relationship with not just your engagement ring.
Gemstones are so durable
A few are mineraloids not true minerals and are including here: opal, amber, and moldavite. Foremost is durability - it must not easily corrode away, nor can it be brittle. It is so durable that nearly all of the gold ever mined is still in circulation or storage. In some cases, the names are true misnomers, such as Green Amethyst for prasiolite-a transparent green variety of quartz.
In most cases, these variety names are historical, as the gemstones were not recognized as being varieties of other minerals until well after the name was in common use such as aquamarine, emerald, and heliodor as varieties of beryl. And that is related to the third characteristic, ductility. You can see the options are endless and when you are commissioning a piece, why compromise a thing when you can choose!
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.
