These can be the difference in reality to getting a collectible piece or getting a knock off or fake. This is place where the many shady characters come into play. There are many places for a person to research this highly collectible genre. Another great place to check is the internet. Some even alert people to the many fake scams that are currently out there. With this explosion has been an increase of fake Jewellery to go along with it. This has become a very hot topic in more recent days and a collector should be aware of it.

Nowadays such a distinction is no longer made by the trade. Rare or unusual gemstones, generally meant to include those gemstones which occur so infrequently in gem quality that they are scarcely known except to connoisseurs, include andalusite, cassiterite and bixbite. Some minerals can be very beautiful, but they may be too soft and will scratch easily (such as the mineral fluorite). Fluorite is extremely colorful and pretty but has a hardness of only 4 on the hardness scale and has four perfect cleavage directions, which makes it only an oddity as a cut gem.

Opals contain almost one-third water and are therefore particularly vulnerable to even moderate temperature changes. Remove from heat and allow the gemstones to soak in the solution until it cools. Thermal shock happens when a stone is instantly transported from one extreme temperature to another. They are all nature's gifts to us. There are more than 40 popular gem varieties and many rarer collector gemstones.
