Collecting Loose Gemstones
By Lee MacRae
Gemology is a term referring to the profession, science, and even art of evaluating and identifying gemstones from loose gemstones to natural diamonds. Many people take up gemology more as a hobby. They become very interested in starting to collect loose gemstones or loose diamonds. You'll even find some that like to visit different areas nearby to look for raw gemstones. Some hobbyists will learn to cut or tumble the gemstones they find. If this hobby interest you read along as we discuss the various aspects of gemstone collecting.
The first thing you need to do is to get some books from the library or bookstore. You want to learn as much as possible about your new hobby. The more you understand about gemstones the wiser will be your purchases. You'll know exactly what to buy.
First on the list to evaluate is gemstone color. Without a doubt, gemstones are the most intensely colored naturally occurring materials you can find. Gemstones are so related to color that they have even lent their names to specific colors. You've no doubt heard about emerald green, ruby red, sapphire blue, jade green, turquoise or aquamarine. Gemstones are valued much higher the closer they come to the natural spectral colors of violet, blue, green,, orange and red. They are valued much less the more they move away from the spectral color.
The cut of the stone is extremely important and is used not only to appraise diamonds but gemstones in general as well. A precision cut gemstone showcases the pure color of the stone, lessen any inclusions and exhibits good overall symmetry and proportion. One way to determine the precision in the cut of the stone is to consider how evenly it reflects light over the stones complete surface. If the gemstone is cut to shallow much of the light will refract out of the gem rather than reflecting internally. Gemstone color will be washed out.
Our next consideration is the clarity of the gemstone. Clarity is the term that refers to the internal conclusions or flaws of the gemstone. Any large flaws can easily be seen with the naked eye with others needing to be magnified 10X
Another consideration is the duo of size and weight. Because gemstones can vary greatly in density and specific gravity. Weight and size are not necessarily equal across the board. Take the example of a diamond that weighs 1.00 carats and an equal sized Sapphire would weigh more than 1.20 carats. An emerald stone would be about 0.95 carats and an Alexandrite stone would be about 1.23 carats.
Although gems are frequently used in 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 gemstone and Think of it as a mini sculpture or piece of art to be highly treasured for its beautiful colors and the finish you apply to it. And unlike some hobbies that require you to pay for your specimens you can use vacation time to actually hunt for raw gemstones in stead of buying. In the United States in Utah You can find Topaz, Garnet, Petrified Wood, Jasper and Obsidian. And if you travel to Canada you will find nephrite jade in Dease Lake, British Columbia or labradorite on Tabor Island, as well as ammolite from Lethbridge, Alberta. Think of gemstone collecting for the great hobby it is.
