Many people, young and old, say collecting semi-precious and precious gemstones like
loose diamonds or
loose gemstones is a passionate hobby. They simply love the beauty and the colors Of the assorted number of gemstones you can find just about everywhere in the world. This article will examine the things you need to know in starting in this interesting hobby.
The first thing you need to do is to get yourself some reading material. You want to know as much as you possibly can about precious and semiprecious gemstones. The more you learn about the hobby of gemstones the wiser will be your purchases. You will know exactly what you are looking at.
To start with, an important aspect in gemstone evaluation is color. Gemstones are the most intensely colored naturally occurring materials you can find. Gems have become so synonomous with color, they have even lent their names to specific colors. Everyone knows ruby red, emerald green, sapphire blue, aquamarine, turquoise, and jade green Gemstones become higher in value they closer they are to natural spectral colors of violet, blue, green,, orange and red. They are valued much less the farther they are from the pure spectral color.
Gemstone cut is very important and factors highly into the appraisal of not only diamonds but along with your gemstones. A precision cut will highlight the gemstone's color, diminish any inclusions, and exhibits good overall symmetry and proportion. One way to determine the precision of gemstone cut is to consider how well and consistent it reflects light throughout its surface. If the gemstone is cut to shallow much of the light will refract out of the gem instead of reflecting internally. Gemstone color will be washed out.
Next to look at is the aspect of clarity. Clarity refers to the the internal conclusions or flaws of the gemstone under consideration. Larger flaws you can usually see with your naked eye while others require close examination using a 10X magnification.
Next to consider are weight and size. Save for pearls and corals, all gemstones are priced by the unit, carat. One carat equals a 0.2 grams. You should know however that weight and size are not the same in gemstones. Density or specific gravity can very. Take a diamond that is 1.00 carats in weight and you will find that a similar sized ruby or sapphire is 1.20 carats.
Collecting gemstones as a hobby can be very enjoyable and could be rewarding as well over time. It doesn't have to be very expensive and yet you can buy some very beautiful items. Many people love to set aside vacation or weekend time to go hunting gemstones. Take the example of the US. In Maine you can find Tourmaline, Beryl, Rose Quartz, Pearl, Topaz, Amazonite, Clear & Smoky Quartz and Aquamarine. Or ou can take a longer vacation and find opal in Coober Pedy, Andamooka or Mintabie in South Australia, topaz in Torrington, New South Wales, Australia or hunt the quartz regions in Yellowdine Lake in Western Australia.

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.
