How To Collect Loose Gemstones
By Lee MacRae
Gemology is a term referring to the art, profession and science of evaluating and identifying gemstones from loose gemstones to natural diamonds. Many people take up gemology more as a hobby. They become interested in collecting and evaluating loose diamonds or loose gemstones. You'll even find some that like to travel to different areas to look for raw gemstones. Some hobbyists will learn to cut or tumble the gemstones they find. If this hobby interest you then read along as we show you the various factors in gemstone collecting.
The first thing you need to do is to visit the library and get some books. You want to understand as much as possible about your new hobby. The more you understand about each kind of gemstone the wiser will be your purchases. You'll know exactly what to look for in a quality stone.
To start with, an important aspect in gemstone evaluation is color. Gemstones are the most intensely colored natural material available on earth. These materials are so related to their color that they've even had their names combined with associated colors. Everyone knows ruby red, emerald green, sapphire blue, aquamarine, turquoise, and jade green Gemstones will have a higher value when they are equal in color to the spectral colors of orange, green, yellow, violet and blue. They are valued much less when they are lighter or darker than the pure spectral color.
The cut of the gemstone is an important aspect to consider in evaluating gemstones. The gemstone must be cut correctly to reflect light properly. A gemstone with the poor cut can't reflect the light consistently over its surface. The color hue, color tone and saturation will never look consistent.
The next factor to look at is the stone's clarity. This is talking about the gemstones purity or the lack of internal inclusions, internal particles or spots within the crystal structure. Obviously, stones with a lack of flaws will make a gemstone very valuable.
Gemstones are often categorized according to their size aspect because of being more uniform than carat weight. But two different gemstones may be of the same size but have different carat weights that result in different prices as well. This is due to the difference of relative density or specific gravity depending upon the chemical composition and crystalline structure. Normally a one carat brilliant round diamond with standard proportions will be approximately 6.5 mm in diameter. A comparable round brilliant ruby of the same size and proportions will weigh approximately 1.55 carats.
Getting involved in collecting gemstones can be very enjoyable and rewarding in the long run. 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 looking for gemstones. For example in Florida you can find Chalcedony and Conch Pearl. And if you like to travel farther you can find opal at Lightning Ridge in NSW, Austalia, topaz in Mt Surprise or O'Briens Creek in Queensland, Australia or check out the Moonstone regions in Moonstone Hill, Queensland, Australia.

Weighing 138.7 carats, the Rosser Reeves Ruby is one of the world's largest and
finest star rubies. This Sri Lankan stone is renowned for its great color and
well-defined star pattern. Advertising mogul Rosser Reeves, who donated the
piece to the Smithsonian in 1965, carried it around as a lucky stone, referring
to it as his baby. He often stated that he had acquired the stone at an auction
in Istanbul in the mid-1950s. He actually bought the stone from Robert C. Nelson
Jr. of New York who was acting on behalf of Firestone & Parson of Boston.
Firestone & Parson were selling the stone for Mr. Paul Fisher of New York. Mr.
Robert Fisher, Paul's father, had bought the ruby at an auction in London in
1953. At the time the ruby then weighed just over 140 carats, but was very
heavily scratched, and a few carats were removed in the repolishing. The
repolishing also helped to center the stone's star. Articles in the New York
World-Telegram and The Sun in 1953 mentioned this fabulous gemstone.
