Collecting Prescious And Semi-Prescious Gemstones
By Lee MacRae
Gemology is the art, profession and science of evaluating and identifying gemstones from loose gemstones to natural diamonds. Many people take up gemology as a passionate hobby. They become interested in collecting loose gemstones or loose diamonds. You'll even find some that like to travel to different areas close by to look for rough gemstones. Some even tumble or learn to cut their own gemstones. If you have an interest in this hobby read along as we discuss the different aspects of this hobby.
The first step in becoming a gemstone collector the smart way is by acquiring knowledge about them. By taking a quick trip to the library or local bookstore you can locate all you need to know about the subject that will make you an informed buyer.
First on your list to look at should be the color of the gemstone. You'll want the stone to be as close in color as possible to the pure spectrum colors. This means red, orange, yellow, green, blue, and violet. Generally, the prices very pale or very dark precious and semi precious stones are lower.
Gemstone cut is an important factor to consider in evaluating gemstones. The stone has to be cut correctly to reflect light properly. A stone that has a poor cut will not reflect light consistently over its entire surface. The hue, tone and color saturation will always look inconsistent.
Our next consideration is the issue of gemstone clarity. Clarity is the term that refers to the internal flaws ( known as inclusions) or the outside blemishes of a stone. Larger flaws can be seen with the unaided eye while others require close examination using a 10X magnification.
Gemstones are often listed according to their size criteria since it is more uniform than carat weight. But different gemstones may be the same size but have different carat weights that result in different in prices as well. This is due to the nature of gemstone difference of specific gravity and depends on the materials chemical composition and crystal structure type For example, a one carat round diamond with standard proportions will be approximately 6.5 mm in diameter. A comparable round brilliant ruby of the same size and proportions will weigh in at 1.55 carats.
Although gems are frequently used in jewelry, they are perfectly good collectibles in their own right. In fact, there are many attractive and interesting gemstones that are too fragile or too large to be used in jewelry. Look at each loose gemstone and consider it as a piece of art and value it for its unique nature and vibrant colors. And in this hobby you don't have to always lay out cash because you can find your raw materials through field trips In the United States in Georgia you can find Ruby, Beryl, Amethyst, Citrine, Garnet and Quartz. And in Canada you can find opal in the Okanagan, British Columbia or amazonite (microcline) near Eganville, Onttario and even Ammolite, a rare gemstone found only in southern Alberta. Take up gemstone collecting and you won't regret it.

Hints About loose natural gemstones
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.
