Starting To Collect Loose Gemstones
By Lee MacRae
Why collect loose gemstones you ask? For many people it's because they are very beautiful items. And just like natural diamonds they can become extremely valuable over the years. Many in this hobby love to collect and work with the wide variety of gemstones available today. Follow along as we discuss the hobby of loose gemstone collecting.
Right at the beginning, what you need is to visit the library and get some books. You want to understand everything there is to know about the subject of gemstones. The more you know about gemstones the wiser will be your purchases. You'll know exactly what to look for in a quality stone.
The first criteria you need to evaluate is stone color. Without a doubt, gemstones are the most intensely colored natural material available on earth. Gems have become so synonomous with color, they've even had their names combined with associated colors. You've no doubt heard about emerald green, ruby red, sapphire blue, jade green, turquoise or aquamarine. Gemstones are valued much higher the closer they are to the colors in the spectrum of violet, blue, green,, orange and red. They drop in value the farther they deviate from the pure natural color.
The cut of the stone is extremely important and is used not only to appraise diamonds along with gemstones. A precision cut gemstone highlights the natural color of the gemstone, diminishes its inclusions, and show off its symmetry and proportions. One way of determining the excellence in the cut is to look at how well and consistent it reflects light throughout the surface of the stone. If the gemstone is cut to shallow much of the light will refract out of the gem rather than reflecting inside the stone. Gemstone color will be washed out.
A third consideration is the clarity of the gemstone. This is talking about the stones purity with no internal conclusions, spots, or particles within the crystal structure. Without a doubt, zero flaws would make the gemstone highly valuable.
Next to consider are size and weight. Other than the corals and pearls gemstones are priced by the carat. One carat is the equivalent of 0.2 grams However you should know size and weight and gemstones are not the same. Density or specific gravity can vary in gemstones. Take a diamond that weighs 1.00 carats and you will see that a similar sized ruby or sapphire is 1.20 carats.
Taking up the hobby of gemstones can be very enjoyable and could be rewarding as well over time. It doesn't have to be very expensive and yet you can end up with some very beautiful stones. Many people love to take vacations to go looking for gemstones. Take the example of the US. In Maryland you can search for Beryl and Clam Pearl. And if you like to travel farther you can find opal in Coober Pedy, Andamooka or Mintabie in South Australia, topaz in Beechworth, Victoria or check out the Moonstone regions in Moonstone Hill, Queensland, Australia.

In general zircon is transparent to translucent. Impurities cause the various
color. Zircons with a cat's eye effect are known but rare. Some crystals contain
radioactive thorium and uranium. Over time, the radioactivity breaks down the
crystal structure so that such stones (usually green) tend to an amorphous
structure, with a lower refractive index and luster than the crystalline type.
These slightly radioactive zircons are very rare in the trade, but highly prized
by collectors and pose no heath threat to its wearer.
