By Lee MacRae
The term gemology refers to the science, art and profession of identifying and evaluating gemstones from loose gemstones to natural diamonds. A number of people taken up this profession more as a hobby. They become very interested in starting to collect items like loose gemstone or natural diamonds. Some people even begin to travel to various areas nearby to look for 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 different aspects of this hobby.
The first thing you need to do is to get yourself some books on gemstones. You want to learn as much as you possibly can about precious and semiprecious gemstones. The more you learn about gemstones the wiser will be your purchases. You need to be as informed as possible.
Color is a very important part in giving value to a gemstone. The closer a color is to its purer spectral value the more valuable it is. Traditionally, these specter colors include violent, blue, green,, orange and red. Colors that tend to be darker or palerthan a pure color tend to be less valued.
Gemstone cut is very important and is used not only to appraise diamonds but gemstones as well. A precision cut gemstone showcases the gemstone's color, diminish any inclusions, and show off its symmetry and proportions. One excellent method to determine the precision in the cut of the stone is to consider if it is able to reflect light on a consistent level over the stones complete surface. If the stone is cut on the shallow side most of this light were refracted away rather than reflecting inside. The gem appears washed out.
The clarity in a stone is the next item to consider. When we talk of clarity it relates to a stones relative freedom from inclusions or blemishes. The gemstone without flaws is definitely worth much more. To determine the flaws not seen with the unaided eye requires a 10X gemstone loupe or gemstone microscope. Most hobbyists will use an inexpensive 10X gemstone or jewelers loup for examining coins, stamps and of course gemstones.
The next factors to consider our size and weight. Save for pearls and corals, all gemstones are priced by the carat. One carat is the equivalent of 0.2 grams Be aware however, that weight and size are not always equal and gemstones. Density or specific gravity can very. Take a diamond that is 1.00 carats in weight and you will find that a similar sized sapphire or ruby would weigh 1.20 carats.
Though you may find gemstones used a lot in jewelry, they are perfectly good collectibles in their own right. In fact, there are many attractive and interesting 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 use vacation time to actually hunt for raw gemstones in stead of buying. In the US in Utah You can find Topaz, Garnet, Petrified Wood, Jasper and Obsidian. And in Canada you can hunt for nephrite jade in Dease Lake, British Columbia or sodalite and rose quartz near Bancroft, Ontario and even amethyst from Nova Scotia. Think of collecting gemstones as a great hobby and pastime.
