How To Collect Loose Gemstones


By Lee MacRae


Gemology is a term referring to the art, profession and science of evaluating and identifying rocks known as natural diamonds or loose gemstones. A number of people taken up gemology as a hobby. They collect and evaluate loose diamonds or loose gemstones. Some people even begin to travel to different areas to look for rough gemstones. Some hobbyists will learn to cut or tumble the gemstones they find. If this hobby interest you then read along as this article discusses the things you should know to start this hobby.


To begin with your first priority is to get yourself some books on gemstones. You want to learn everything there is to know about your new hobby. The more you understand about gemstones the wiser will be your purchases. You'll know exactly what to look for in a quality stone.


Color is a subjective idea but a very important part in evaluating a gemstone. The closer a color is to its pure spectral color the more valuable it is. Traditionally, these specter colors are orange, green, yellow, Violet and blue. Colors that are darker or palerthan a pure color diminish the value of the stone.



Gemstone cut is very important and is used not only to appraise diamonds along with gemstones. A precision cut gemstone showcases the natural color of the gemstone, diminish any inclusions, and show off its symmetry and proportions. One way to determine the precision regarding the cut of the gemstone is if it is able to reflect light on a consistent level throughout the surface of the stone. If the stone is cut on the shallow side most of this light were refracted away rather than reflecting inside. Gemstone color will be washed out.


Our next consideration is the issue of gemstone clarity. The aspect of clarity 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 need a 10X magnification.


Gemstones are often listed according to their size criteria because 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 or relative density and depends on the materials chemical composition and crystal structure type For example, a one carat round diamond of typical proportions will be approximately 6.5 mm in diameter. A ruby that is the same size will weigh approximately 1.55 carats.


Although gemstones are normally used for jewelry, they are perfectly good collectibles in their own right. Actually there are many interesting and attractive gems that are just too big or fragile to be used for jewelry. Look at each loose gemstone and consider it as a piece of art and value it for its unusual nature and for the craftsmanship of the artisan who shaped it. 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 Maine you can find Tourmaline, Beryl, Rose Quartz, Pearl, Topaz, Amazonite, Clear & Smoky Quartz and Aquamarine. And in Canada you can find rhodonite at various locations in British Columbia or amazonite (microcline) near Lac St-Jean, Quebec and even Ammolite, a rare gemstone found only in southern Alberta. Think of collecting gemstones as a great hobby and pastime.

Topaz can be found in streams, rivers and in gravel deposits. It is found mainly
in gem pegmatites where the presence of fluorine can be found. Flourine provides
a rich environment for the stones to grow into very large crystals. In fact,
without the presence of Flourine topaz would not exist. Topaz crystallizes
orthorhombically and develops columns with square and diamond shapes planes with
multisurfaced heads. Topaz can also be found in cracks and cavities where a
combination of Flourine and silica and alumina which was released by very hot
temperatures caused the gems to form. Chromium Oxide is what provides its
beautiful color.
