So You Want To Collect Gemstones
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 as a passionate hobby. They become interested in collecting loose diamonds or loose gemstones. A number of these hobbyists start to travel to various areas nearby 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 this article discusses the various factors in gemstone collecting.
First off you'll need the knowledge on each of the gemstones out there. This knowledge will help you to know what exactly you're looking for and prevent you from wasting your money. A knowledgeable buyer is a wise one.
First, color is a major part in giving value to a gemstone. The closer the color comes to its purer spectral value the more valuable it is. Traditionally, these specter colors are yellow, blue, Violet, green, orange and red. Gemstones colors that are darker or paler than a pure spectral color tend to be less valued.
How a stone has been cut is the second most important factor to consider before buying. The precision of cut is the factor that determines the amount of light the gemstone stone will reflect. The cut will factor highly in the brilliance of the stone and its final value.
The next factor to consider is the clarity. This refers to the purity of the gemstone or the absence of internal inclusions, spots, or particles within the crystal. Obviously, stones with a lack of flaws will make a gemstone very valuable.
You will often find that gemstones are often listed according to their size because of being more uniform than carat weight. But different gemstones may be the same size but different carat weights and consequently, different prices as well. This is due to gemstone difference of specific gravity or relative density depending upon the materials chemical composition and crystal structure type For example, a one carat 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 in at 1.55 carats instead.
Collecting various gemstones can be a great hobby. And there are so many different types when it comes to gemstones. You can start collecting gemstones like Malachite, Spinel or Kornerupine for instance. The varieties are nearly endless. And if you like a hands on hobby you can go gemstone hunting and find the raw materials instead of buying them. Just in the United States in Idaho you'll find Garnet, Opal, Agate, Obsidian and Sapphire.
