How To Collect Gemstones
By Lee MacRae
Gemology is the science, art and profession of identifying and evaluating rocks known as natural diamonds or loose gemstones. A number of people taken up gemology more as a hobby. They become interested in making a collection of items like loose gemstone or natural diamonds. You'll even find some that like to visit different local areas to look for rough gemstones. Some even tumble or learn to cut their own gemstones. If this hobby interest you then read along as this article discusses the in and outs of gemstone collecting.
The very first step in starting the hobby of collecting gemstones the smart way is by acquiring knowledge about them. By taking a quick trip to the library or local bookstore you can find books on the subject that will prevent you from making mistakes at the start.
First, color is a major part in evaluating a gemstone. The closer the color comes to its purer spectral value the more valuable it is. Remember that the spectral colors are yellow, blue, Violet, green, orange and red. Gemstones colors that are paler or darker than the pure spectral color diminish the value of the stone.
Gemstone cut is very important and is used not only to appraise diamonds but gemstones as well. An excellent cut will showcase the gemstone's color, lessen any inclusions and exhibits good overall symmetry and proportion. One excellent way to determine the excellence in the cut is to look at how well it reflects light on a consistent basis over the stones complete surface. If the stone is cut on the shallow side most of this light were refracted away rather than reflecting inside. That will make the gem seem washed out and windowed.
Next to look at is the aspect of gemstone clarity. Clarity refers to the the internal conclusions or flaws of the gemstone. Any large flaws are visible to the unaided eye with others requiring a 10X magnification.
You will note that gemstones are categorized according to their size criteria because it is more uniform than carat weight. But two different gemstones may be the same size but different carat weights and consequently, different prices as well. This is due to gemstone difference of specific gravity and depends on the materials chemical composition and characteristic crystalline structure. For example, a one carat round diamond with standard proportions will be approximately 6.5 mm in diameter. A comparable a brilliant ruby of the same proportions in size will weigh approximately 1.55 carats.
Collecting various gemstones can be very rewarding hobby. And there is such a variety in precious and semi precious stones that you can collect. You can collect gemstones like Agate, Spinel or Kornerupine for instance. The varieties are nearly endless. And if you like a hands on hobby you can go hunting for raw gemstones. Take the example of the US. In New Jersey you can find Smoky Quartz, Agate, Pearl and Prehnite.

The name �tourmaline� was derived from the Singhalese expression �tura mali� which translates as �stone of mixed colors�. Because tourmalines are a complex crystal often mixed with elements such as aluminum and boron, it occurs in more colors than most minerals, and can even have more than one color or hue. Green and red are the better known colors as well as multicolored stones. Depending on the angle of view, the color will be different or at least show a different intensity. In the 17th century it was found that tourmalines become electrically charged when under pressure or heated. This discovery attributed it with magical powers. Some believed the pink tourmaline attracted love, and the green brought success.

Even the hardest gemstone variety can be vulnerable to breakage if it has
inclusions that weaken the crystal structure. Exercise common sense: if you have
a ring set with a softer gem variety or an included stone, take it off before
strenuous activity. Even the hardest gemstones like Diamonds, Rubies and
Sapphires can shatter with a single well-placed blow especially if they have
inclusions, which weaken the crystal structure.

The Archduke Joseph...this 76.45-carat diamond gets its name from from Archduke
Joseph August (1872-1962), a previous owner of the gem and a prince of the
Hungarian line of the Hapsburg dynasty. The Archduke Joseph is a colorless
diamond; it possesses the most notable characteristic of the best Golconda
diamonds, namely a high internal clarity. Thus its D-color certification. It is
cut in a rectangular cushion shape, perhaps a style of cutting that is not
entirely unfitting with its Indian origin. The diamond originally weighed 78.54
carats but was slightly recut in the late-1990's by Molina Fine Jewelers down to
its present 76.45-carat weight. The diamond has been graded as being Internally
Flawless.
