Collecting Prescious And Semi-Prescious Gemstones
By Lee MacRae
The term gemology refers to the profession, science, and even art of evaluating and identifying rocks known as natural diamonds or loose gemstones. A number of people taken up this profession more as a hobby. They become interested in collecting loose diamonds or loose gemstones. You'll even find some that like to travel to various neghbourhood locations to look for rough gemstones. Some hobbyists will learn to cut or tumble the gemstones they find. If this hobby interest you then follow along as we show you the in and outs of gemstone collecting.
The first step in beginning this hobby the intelligent way is by acquiring knowledge about them. By visiting a local library you can find everything you need to know that will help you to know exactly what you should do.
First on the list to evaluate is gemstone color. It is a fact that gemstones are the most intensely colored naturally occurring materials you can find. These materials are so related to their color that they've even had their names combined with associated colors. Everyone knows ruby red, emerald green, sapphire blue, aquamarine, turquoise, and jade green Gemstones are valued much higher the closer they are to the colors in the spectrum of yellow, blue, violet, green, orange and red. They are valued much less the farther they are from the pure spectral color.
Gemstone cut is very important and factors into appraisal of diamonds but gemstones in general as well. An excellent cut will showcase the gemstone's color, diminish any inclusions, and show off its symmetry and proportions. One way to determine the precision regarding the cut of the gemstone is how consistent and well, it reflects the light over its entire surface. If the gemstone is cut to shallow much of the light will refract out of the gem instead of reflecting inside. That will make the gem seem washed out and windowed.
The next factor to consider is the clarity of the stone under consideration. This means the purity of the stone or the lack of internal inclusions, particles or spots inside the crystal. Needless to say, stones with no flaws are hard to find and make your stones very valuable.
Gemstones are often categorized according to their size because of being more uniform than carat weight. But different gemstones may be of 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 or relative density and depends on the materials chemical composition and crystal structure type Normally a one carat brilliant round diamond of typical 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 instead.
Although gemstones are normally used for jewelry, loose gemstones are great for collecting. In fact, there are many attractive and interesting gemstones that are simply too big and fragile for use in jewelry. Take each loose gemstone and think of it as a piece of art, a miniature sculpture to be treasured 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 Virginia you can find Amethyst, Garnet, Beryl and Moonstone. And in Canada you can find rhodonite at various locations in British Columbia or amazonite (microcline) near Lac St-Jean, Quebec along with black spinel in Burgess and bathhurst Townships in Ontario. Take up gemstone collecting and you won't regret it.

The GIA recently released a new cut grading system and it appears they have
finally conquered this beast. Rather than calculating how close a cut came to an
�ideal� set of proportions, the new system is based on how the individual
elements combine to affect the appearance of a diamond. In addition, they were
able to install some flexibility in the system to allow for personal preferences
, with table size being a prime example.

The cut of a gemstone is also very important. It is more common to see a bad cut
than it is to see a good cut, especially in very precious stones. A good cut is
one that is symmetrically and beautifully proportioned, perfectly polished and
makes the most out of the stones natural beauty.
