Collecting Prescious And Semi-Prescious Stones


By Lee MacRae


Why would anyone collect items like loose gemstones, you ask? Well for one thing they are very beautiful items. And like their higher counterpart, natural diamonds they can appreciate in value over time. Many in this hobby love to collect and work with the wide variety of gemstones available today. Read long as we examine the loose gemstones hobby.


The first thing you need to do is to get yourself some books on gemstones. You want to understand as much as you possibly can about precious and semiprecious gemstones. The more you know about the hobby of gemstones the less likely you are to make a mistake. You'll know exactly what to look for in a quality stone.


The first criteria you need to evaluate is stone color. It is a fact that gemstones are the most intensely colored natural material available on earth. 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 when they are equal in color to the spectral colors of yellow, blue, violet, green, orange and red. They become less valuable when they are lighter or darker than the pure spectral color.



Cut is one of the all-important 4Cs and factors into appraisal of diamonds but along with your gemstones. A good cut showcases the gemstone's color, diminishes its inclusions, and highlight the proportions and symmetry of the stone. One way to determine the precision of its cut is to check how well it reflects light on a consistent basis throughout the surface of the stone. If the stone is cut on the shallow side most of the light will refract out instead of reflecting internally. Gemstone color will be washed out.


The clarity of a gemstone is our next factor. Clarity refers to the absence of flaws or blemishes inside the stone. The gemstone without flaws is obviously valued highly. To examine flaws not seen with the naked eye requires a 10X gemstone clarity magnifier or gem microscope. Many hobbyists will use a jewelers diamond gemstone loupe 10X for viewing stamps, coins, beads as well as gems.


Next on the agenda is the duo of size and weight. Because gemstones can vary greatly in density and specific gravity. Weight and size are not necessarily equal across the board. If you have a diamond that weighs 1.00 carats a ruby 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.


Collecting gemstones can be very rewarding hobby. And there are so many different types when it comes to gemstones. You could try collecting Hematite, Topaz or Turquoise for example. The varieties are nearly endless. And if money is tight you can go hunting for raw gemstones. Take the example of the United States. In Missouri you can hunt for Pearl, Fluorite, Pyrite and Calcite.
