Inspired by Jewellery
When you can spend a fraction of the cost why spend a ton of money for an item of jewellery? Their hair all done up, a pretty dress on and amazing jewelry. Wish no further, today there are many knock off companies that design jewellery to look like the stars. Even if it isn't exact, it comes extremely close and looks great. But if it still looks amazing and purchased at a great price, make it yours.
They specifically want to recreate what sparkled on the red carpet so you too can feel beautiful. Have you ever seen pictures of celebrities walking the red carpet and thought to yourself that I want to look like that? So, neither should you at such a crazy price. It is important to realize that most of the time these celebrities are borrowing their jewellery anyways, they aren't even purchasing the stuff! Most of these knock off stores have great quality items with top grade CZ and sterling silver.
All gemstones have some characteristics
Many gemstones are used in even the most expensive jewellery depending on the brand name of the designer, fashion trends, market supply, treatments etc. Others are too common and are given a semi-precious status. Most gemstones have good hardness and a high index of refraction.
All gemstones have some characteristics falling short of perfection though; even the seemingly perfect Diamond has four directions of cleavage. Since quartz is everywhere especially in common dirt and dust. Any material that is softer may be scratched during ordinary wear. Nevertheless, diamonds, rubies, sapphires and emeralds still have a reputation that exceeds those of other gemstones.
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.
