How To Collect Gemstones

By Lee MacRae

Gemology is 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 more as a hobby. They become interested in collecting and evaluating loose gemstones or loose diamonds. Some people even begin to visit different areas nearby or in other countries to hunt for raw or rough gemstones. Some of them will even tumble or finish off the gemstones themselves. If this sounds like a hobby you would like to get involved in read along as this article discusses the things you should know to start this hobby.

Right at the start you need to learn all you can on each of the gemstones out there. This will help you to know the properties of each stone and prevent you from wasting your money. Without the proper knowledge you can make costly mistakes.

The first item to take into account will be the color of the stone. You want the gemstone that is as close as possible to the pure spectral colors. The spectral colors are red, orange, yellow, green, blue, and violet. The prices of very dark are very pale stones are lower than the vibrant colors.

The cut of a gemstonestone is the next factor to consider before buying. The precision of cut is the factor which determines how much light is reflected by the gemstone. It will ultimately determine the brilliance of the stone and how much it will be valued.

Next to look at is the aspect of gemstone clarity. The aspect of clarity refers to the internal conclusions or flaws of the gemstone. Any large flaws can easily be seen with the unaided eye while others require close examination using a 10X magnification.

Next thing to look at is the duo of size and weight. Due to their nature gemstones can vary in density or specific gravity. Weight and size are not necessarily equal across the board. Take the example of a diamond that weighs 1.00 carats and an equal sized Sapphire would weigh more than 1.20 carats. An Emerald of equal size would be approximately 0.95 carats while an Alexandrite gemstone would be about 1.23 carats.

Though you may find gemstones used a lot in jewelry, loose gemstones are great for collecting. Actually there are many interesting and attractive gemstones who that are just too big or fragile to be used for jewelry. Take each loose gemstone and think of it as a piece of art, a miniature sculpture to be treasured for its unique nature and vibrant colors. 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 Wyoming you can find Agate (including Moss Agate), Jade, Ruby, Jasper, Bloodstone as well as Star Sapphire. And in Canada you can find nephrite jade in Mount Sidney Williams, British Columbia or labradorite on Tabor Island, and even hessonite garnet in Asbestos, Quebec. Take up gemstone collecting and you won't regret it.

The common opal is quite a departure from the precious opal. There are several
different types of common opals: the milk opal, opals with blue and green tints,
resin opal, and a wood opal. There are also opals that can be found around hot
springs and geysers. They are a clear glass opal made up of geyserite. There are
other varieties of opals most notably the fire opal and Peruvian opal. Mexico
and Mesoamerica is the chief source of the fire opal. They come from the Mexican
high country where they can be found in rock surrounding extinct volcanoes. It
is extracted from open-pit mines in the canyons and valleys there. It should be
noted that more durable fire opals are found in drier region. The drier the
region the more durable the opal will be. While Mexico produces the most fire
opals they can be found in Honduras, Ethiopia, United States, Australia, Canada,
Turkey and areas in former Russian states.
