The Best Information On Gemstones
Featured Gemological ArticleHow To Collect Loose Gemstones
By Lee MacRae
Gemology is a term referring to the profession, science, and even art of evaluating and identifying gemstones from natural diamonds to loose gemstones. A number of people taken up this profession as a passionate hobby. They collect and evaluate loose gemstones or loose diamonds. A number of these hobbyists start to visit various local locations to look for rough gemstones. Some hobbyists will learn to cut or tumble the gemstones they find. If you have an interest in this hobby then read along as we reveal the various aspects of gemstone collecting.
The first thing you need to do is to get yourself some books on gemstones. You want to know as much as you possibly can about precious and semiprecious gemstones. The more you know about gemstones the better off you'll be. You will know exactly what you are looking at.
First, color is a major part in giving value to a gemstone. The closer the color comes to its pure spectral color the more valuable the stone becomes. Traditionally, these specter colors are orange, green, yellow, Violet and blue. Colors that tend to be darker or paler are considered a lower value.
How the gemstone has been cut is the second most important value determination to consider before a purchase is made. How precise the cut is is the factor that determines the amount of light the stone will reflect. It will ultimately determine the brilliance of the stone and how much someone will pay for it.
The clarity in a stone is our next factor. Clarity refers to the amount of inclusions (trace elements or large particles of other elements or minerals) that a gem has. A flawless gemstone is definitely worth much more. To determine the flaws not seen with the unaided eye requires a 10X gemstone clarity magnifier or gem microscope. Serious hobbyists will get an inexpensive 10X gemstone or jewelers loup for viewing stamps, coins, beads as well as gems.
Next thing to look at is the duo of size and weight. Because gemstones vary and specific gravity or density. Weight and size are not equal for each and every stone. Take the example of a diamond that weighs 1.00 carats and an equal sized ruby would weigh 1.20 carats instead. An Emerald of equal size would be approximately 0.95 carats while an Alexandrite would be about 1.23 carats.
Though you may find gemstones used a lot in jewelry, they are perfectly good collectibles in their own right. Actually there are many interesting and attractive gems that are simply too big and fragile for use in jewelry. Take each gemstone and consider it as a piece of art and value it for its unusual nature and for the craftsmanship of the artisan who shaped it. And unlike many hobbies where you have to buy everthing you can actually go hunting for raw gemstones in the field. In the United States in Michigan you can find Agate, Chlorastrolite and Hematite. And in Canada you can hunt for nephrite jade in the Frances Lake area in the Yukon Territory or Tourmaline from Chatham Twonship, Quebec as well as the unique deep blue beryl in Canada's Yukon Territory. Take up gemstone collecting and you won't regret it.

"Green amethyst" is a misnomer since the term "amethyst" applies only to the
purple variety of quartz. However, that doesn't stop the marketing of these less
valuable pale amethyst stones after irradiation and/or heat treatments turn the
color green. Properly, after treatment, this stone should be marketed as
Prasiolite or Green Quartz, not green amethyst, and it should not be marketed as
"rare" since there is an abundance of pale lavender quartz which can be treated
to produce a light spring green stone.
