How To Collect Loose Gemstones


By Lee MacRae


Gemology is a term referring to the art, profession and science of evaluating and identifying gemstones from loose gemstones to natural diamonds. A number of people taken up this profession more as a hobby. They become interested in collecting and evaluating loose diamonds or loose gemstones. A number of these hobbyists start to visit different areas nearby or in some cases other countries to look for raw gemstones. Some even tumble or learn to cut their own gemstones. If this hobby interest you read along as this article discusses the in and outs of gemstone collecting.


To start off right you need to learn all you can on each of the gemstones out there. You'll find it very helpful to know the properties of each stone and prevent you from wasting your money. This will help you make informed decisions.


The first item to take into account is gemstone color. You want the gemstone that is as close as possible to the pure colors of the spectrum. This means violet, orange, yellow, green, blue, and red. The prices for very pale or very dark precious and semi precious stones are less per carat.


Gemstone cut is the next factor to consider. The preciseness of the cut determines the amount of light is reflected by the gemstone. The cut will ultimately determine the stones brilliance and how much it will be valued.


Next to look at is the clarity of the gemstone. Clarity is the term that refers to the internal conclusions or flaws of the gemstone. Larger flaws you can usually see with your naked eye while others need a 10X magnification.


Next comes weight and size. All gemstones [except for pearls and corals] are priced by the unit, carat. One carat equals a 0.2 grams. However you should know weight and size are not the same in gemstones. Density or specific gravity can vary in gemstones. If you have a diamond that weighs 1.00 carats, you will find a similar sized ruby or sapphire weighs 1.20 carats.


Collecting gemstones can be a great hobby. And there is a wide range and variety in precious and semi precious stones that you can collect. You can collect gemstones like Emerald, Pyrite or Natural moissanite for example. The varieties are nearly endless. And if you like to save money but love vacations you can go hunting for raw gemstones. Take the example of the US. In Virginia you can find Amethyst, Garnet, Beryl and Moonstone.

The Hobby Of Gemstone Collecting


By Lee MacRae


The term gemology refers to the science, art and profession of identifying and evaluating gemstones from natural diamonds to loose gemstones. A number of people taken up this profession as a passionate hobby. They become interested in collecting items like loose gemstone or natural diamonds. Some people even begin to visit different local areas to look for rough gemstones. Some of them will even tumble or finish off the gemstones themselves. If you have an interest in this hobby follow along as we reveal the in and outs of gemstone collecting.


The very first step in starting the hobby of collecting gemstones the right way is by getting adequate knowledge about them. By visiting a local library you'll find numerous books on gemstones that will make you an informed buyer.


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. Gems have become so synonomous with color, they've even become associated with particular ones. Everyone knows ruby red, emerald green, sapphire blue, aquamarine, turquoise, and jade green Gemstones become higher in value the closer they come to the natural spectral colors of red, orange, yellow, green, blue, and violet. They drop in value the more they deviate from the spectral color.



The cut of the stone is extremely important and is used not only to appraise diamonds along with gemstones. A precision cut gemstone showcases the gemstone's color, diminish any inclusions, and exhibits good overall symmetry and proportion. One excellent method to determine the precision in the cut is to look at how well and consistent it reflects light throughout the surface of the stone. But if a gem is cut too shallow, most of the light will refract out instead of reflecting internally. Gemstone color will be washed out.


The clarity in a stone is the next item to consider. Clarity refers to a stones relative freedom from inclusions or blemishes. The gemstone without flaws is obviously valued highly. To see flaws beyond with the eye can see you need a gem microscope or gemstone clarity magnifier. Serious hobbyists will use a jewelers diamond gemstone loupe 10X for viewing stamps, coins, beads as well as gems.


Next item to look at is the duo of size and weight. Due to the fact gemstones vary and specific gravity or density. Weight and size are not necessarily equal across the board. Take the example of a diamond that weighs 1.00 carats and a sapphire of equal size would weigh 1.20 carats. An emerald stone would be about 0.95 carats and an Alexandrite gemstone would be about 1.23 carats.


Taking up the hobby of gemstones can be very enjoyable and rewarding in the long run. You don't need to spend a lot of money and yet you can build a very exquisite collection. Many people love to set aside vacation or weekend time to go looking for gemstones. Take the example of the US. In New York you can find Beryl, Brown Tourmaline, Rose Quartz as well as Fresh Water Pearl. Or ou can take a longer vacation and find opal at Lightning Ridge in NSW, Austalia, topaz in Killiecrankie, Tasmania or hunt in the garnet fields in Fullarton River in Queensland, Australia.

Agates are a cryptocrystalline (crystals too small to be seen even by a microscope) variety of quartz, also known as Chalcedony. The varieties of Agate or Chalcedony are divided more by character than by color. They are divided into a host of gemstones that have been named for locally common varieties. Some of the more beautiful types have retained their names worldwide, like Carnelian, while other names have faded into obscurity as many of the relatively small local deposits became exhausted.
