Gemology is the art, profession and science of evaluating and identifying gemstones from
loose gemstones to
natural diamonds. Many people take up gemology more as a hobby. They become interested in collecting
loose gemstones or
loose diamonds. A number of these hobbyists start to visit different areas nearby or in some cases other countries to hunt for raw or rough gemstones. Some hobbyists will learn to cut or tumble the gemstones they find. If you have an interest in this hobby follow along as we discuss the in and outs of gemstone collecting.
To start off right you'll need the knowledge on the wide variety of stones available. This knowledge will help you to know what you're buying and prevent you from making mistakes. Get the answer to questions like how, where and what to buy.
To start with, an important aspect in gemstone evaluation is color. Gemstones are the most intensely colored naturally occurring materials you can find. Gemstones are so related to 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 will have a higher value the closer they are to the colors in the spectrum of red, orange, yellow, green, blue, and violet. They become less valuable the farther they deviate from the natural color.
The cut of your gemstone is one of the most important traits when you value gemstone. The gemstone must be cut in a way that reflects light back to the viewer. A poor cut will be muted or washed out. The hue, tone and color saturation will be inconsistent.
The clarity of a gemstone is the next item to consider. Clarity refers to the amount of inclusions (trace elements or large particles of other elements or minerals) that a gem has. A gemstones that is normally found to be clean is obviously worth more. To see flaws beyond with the eye can see you need a gem microscope or 10X gemstone clarity magnifier. Many hobbyists will use an inexpensive 10X gemstone or jewelers loup for viewing their coins, beads, stamps or in our case gemstones.
The next factors to consider our weight and size. Except for corals and pearls, all gemstones are valued by the unit called the carat. A carat is equal to 0.2 grams. However you should know weight and size are not the same in gemstones. Density or specific gravity can very. Take a diamond that weighs 1.00 carats and you will see that a similar sized ruby or sapphire weighs 1.20 carats.
Taking up the collecting of loose gemstones can create an enjoyable hobby and pastime. And there is such a variety in gemstones you can collect. You can collect gemstones like Feldspar (moonstone), Ruby or Andalusite and then try others. The choice and beauty and variety is almost endless. And if money is tight you can go gemstone hunting and find the raw materials instead of buying them. Take the example of the United States. In Alaska you can find White Quartz and Jade.
