Starting To Collect Gemstones
By Lee MacRae
The term gemology refers to the art, profession and science of evaluating and identifying rocks known as natural diamonds or loose gemstones. Many people take up gemology as a passionate hobby. They become interested in collecting and evaluating items like loose gemstone or natural diamonds. A number of these hobbyists start to travel to various neghbourhood locations to look for rough gemstones. Some of them will even tumble or finish off the gemstones themselves. If this hobby interest you then read along as we discuss the different aspects of this hobby.
To start off right you need to read up on each of the gemstones out there. This will help you to know the properties of each stone and prevent you from making mistakes. Without the proper knowledge you can make costly mistakes.
Color is a very important part in the value of the stone. The closer the color of the gemstone is to its pure spectral color the more valuable it is. Traditionally, these specter colors include violent, blue, green,, orange and red. Gemstones colors that are paler or darker than the pure spectral color are considered a lower value.
The cut of the stone is extremely important and is used not only to appraise diamonds but along with your gemstones. A good cut showcases the pure color of the stone, lessen any inclusions and highlight the proportions and symmetry of the stone. One way to determine the precision in gemstone cut is to consider how consistent and well, it reflects the light throughout the surface of the stone. If the gemstone is cut to shallow much of the light will refract out of the gem rather than reflecting inside. That will make the gem seem washed out and windowed.
The clarity in a stone is our next factor. Clarity refers to the absence of flaws or blemishes inside the stone. A perfect gemstone is obviously worth more. To see flaws beyond with the eye can see you need a gemstone loupe (gemstone clarity magnifier) or gem microscope. Serious hobbyists will employ a jewelers diamond gemstone loupe 10X for viewing stamps, coins, beads as well as gems.
The next factors to consider our size and weight. Save for pearls and corals, all gemstones are valued by the unit called the carat. A carat is equal to 0.2 grams. Be aware however, that weight and size are not the same in gemstones. The density and specific gravity can differ in stones. Take a diamond that is 1.00 carats in weight and you will find that a similar sized ruby or sapphire weighs 1.20 carats.
Getting involved in collecting gemstones can give you an enjoyable pastime and also rewarding in the long run. You don't need to spend a lot of money and yet you can buy some very beautiful items. Many people loved to spend weekends to go hunting for raw gemstones. Take the example of the United States. In Utah You can find Topaz, Garnet, Petrified Wood, Jasper and Obsidian. Or you can take the time to travel and find opal at Lightning Ridge in NSW, Austalia, topaz in Torrington, New South Wales, Australia or check out the quartz regions in Cloncurry in Queensland, Australia.

The common opal is quite a departure from the precious opal. There are several
different types of common opals: the milk opal, opals with blue and green tints,
resin opal, and a wood opal. There are also opals that can be found around hot
springs and geysers. They are a clear glass opal made up of geyserite. There are
other varieties of opals most notably the fire opal and Peruvian opal. Mexico
and Mesoamerica is the chief source of the fire opal. They come from the Mexican
high country where they can be found in rock surrounding extinct volcanoes. It
is extracted from open-pit mines in the canyons and valleys there. It should be
noted that more durable fire opals are found in drier region. The drier the
region the more durable the opal will be. While Mexico produces the most fire
opals they can be found in Honduras, Ethiopia, United States, Australia, Canada,
Turkey and areas in former Russian states.

In nature, the emerald is one of the rarest and most valuable of all gems. A fine quality emerald of good brilliant green color and clarity is more valuable than a diamond. The word �emerald� comes from a sanskrit word meaning �the green of growing things�. Nature takes about 1 million years to create an emerald. It is the birthstone for May and ranks 7.5 to 8 on the Mohs Scale of Hardness.
