Collecting Prescious And Semi-Prescious Gemstones
By Lee MacRae
The term gemology refers to the science, art and profession of identifying and evaluating rocks known as natural diamonds or loose gemstones. A number of people taken up gemology more as a hobby. They become very interested in starting to collect items like loose gemstone or natural diamonds. A number of these hobbyists start to visit various locations close by to look for rough gemstones. Some hobbyists will learn to cut or tumble the gemstones they find. If this hobby interest you then read along as we discuss the things you should know to start this hobby.
To begin with your first priority is to get yourself some reading material. You want to learn as much as possible about your new hobby. The more you understand about the hobby of gemstones the wiser will be your purchases. You'll know exactly what to look for in a quality stone.
Color is a subjective idea but 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 are yellow, blue, Violet, green, orange and red. Colors that are darker or palerthan a pure color tend to be less valued.
Gemstone cut is very important and is used not only to appraise diamonds along with gemstones. A precision cut gemstone showcases the natural color of the gemstone, diminish any inclusions, and show off its symmetry and proportions. One excellent method to determine the precision in gemstone cut is to consider how consistent and well, it reflects the light throughout the surface of the stone. If the gemstone is cut to shallow most of this light were refracted away rather than reflecting inside the stone. Gem color appears washed out.
Next up is the clarity of the gemstone. The aspect of clarity refers to the internal conclusions or flaws of a stone being considered. Larger flaws are visible to the unaided eye with the others needing a 10X magnification.
Another consideration is the duo of weight and size. Due to the fact gemstones vary and specific gravity or density. Size and weight are not necessarily equal from stone to stone. If you have a diamond that weighs 1.00 carats an equal sized Sapphire would weigh more than 1.20 carats. An emerald stone would be about 0.95 carats and an Alexandrite gemstone would be about 1.23 carats.
Although gems are frequently used in jewelry, they are perfectly good collectibles in their own right. Actually there are many interesting and attractive gemstones who that are simply too big and fragile for use in jewelry. Look at each loose gemstone and Think of it as a mini sculpture or piece of art to be highly treasured 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 Mount Ogden, British Columbia or pink and dark blueish spinels in Wakefield, Quebec along with amethyst from Nova Scotia. Think of gemstone collecting for the great hobby it is.
