Why I Like Gemstones
Starting To Collect Loose Gemstones
By Lee MacRae
Gemology is the science, art and profession of identifying and evaluating gemstones from natural diamonds to loose gemstones. Many people take up gemology more as a hobby. They become interested in collecting items like loose gemstone or natural diamonds. Some people even begin 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 you have an interest in this hobby then read along as we discuss the various factors in gemstone collecting.
Right at the beginning, what you need is to visit the library and get some books. You want to know as much as you possibly can about the subject of gemstones. The more you know about each kind of gemstone the less likely you are to make a mistake. With adequate knowledge you are less likely to be fooled.
Color is a very important part in the value of the stone. The closer a color is to its purer spectral value the more valuable the stone becomes. Traditionally, these specter colors are orange, green, yellow, Violet and blue. Gemstones colors that are darker or paler than a pure spectral color are considered a lower value.
How a stone is cut is the second most important factor to look at. How precise the cut is determines the amount of light is reflected by the gemstone. It will ultimately ultimately determine the stones brilliance and its final value.
Next to look at is gemstone clarity. Clarity refers to the the internal conclusions or flaws of a stone. Any large flaws you can usually see with your naked eye while others need a 10X magnification.
The next factors to consider our size and weight. All gemstones [except for pearls and corals] are priced by the unit, carat. A carat is equal to 0.2 grams. Be aware however, that weight and size are not always equal and gemstones. Density or specific gravity can vary in gemstones. If you have a diamond that weighs 1.00 carats, you will find a Sapphire or ruby of the same size would weigh 1.20 carats.
Taking up the collecting of loose gemstones can be very rewarding hobby. And there are so many different types in gemstones you can collect. You can start collecting gemstones like Chrysoprase, Amethyst (cardinal gem) or Clinohumite for example. The choice and beauty and variety is almost endless. And if money is tight you can go hunting for raw gemstones. Take the example of the US. In Michigan you can find Agate, Chlorastrolite and Hematite.

Gemstones are generally sold by weight, and not by size. The price will be per
carat, which is one-fifth of a gram. Some gems are heavier than others so the
same weight stone may be a different size! The carat weight also affects the
price: large gemstones are more rare, so the price per carat is higher.

In Australia, Cambodia and Thailand sapphires have developed over millions of
years from rich deposits of molten carbonatite that has a lot of aluminum mixed
with it. At first they were situated deep in the earth's crust where there was a
presence of high pressure and extremely high temperatures. It was basalt
volcanic activity that propelled them to the surface along with other minerals,
and finally they were laid to rest on the valley floors.
