Starting The Hobby Of Loose Gemstone Collecting


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 gemology 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 travel to various areas nearby to hunt for raw or rough gemstones. Some of them will even tumble or finish off the gemstones themselves. If you have an interest in this hobby read along as we reveal the various aspects of gemstone collecting.


To begin with you need to learn all you can on the various gemstones available. This will help you to know what you're buying and prevent you from wasting your money. This will help you make informed decisions.


Color is a very important part in evaluating a gemstone. The closer a color is to its purer spectral value the more valuable it is. Traditionally, these specter colors include red, orange, yellow, green, blue, and violet. Colors that tend to be paler or darker than the pure color tend to be less valued.



Gemstone cut is very important and factors into appraisal of diamonds but you're gemstones as well. A good cut highlights the gemstone's color, lessen any inclusions and exhibits good overall symmetry and proportion. One way to determine the precision in the cut is to look at how well and consistent it reflects light throughout its surface. If the gemstone is cut to shallow most of the light will refract out instead of reflecting inside. That will make the gem seem washed out and windowed.


Next up is the clarity of the gemstone. The aspect of clarity refers to the internal flaws ( known as inclusions) or the outside blemishes of a stone being considered. Larger flaws can be seen with the naked eye with the others needing a 10X magnification.


Gemstones are often listed according to size since it is more uniform than carat weight. But two different gemstones may be the same size but have different carat weights that result in different in prices as well. This is due to gemstone difference in relative density or specific gravity depending upon the materials chemical composition and crystal structure type For example, a one carat round diamond with normal proportions is approximately 6.5 mm around. A comparable round brilliant ruby of the same size and proportions will weigh approximately 1.55 carats.


Taking up the hobby of gemstones can become an enjoyable pastime and also rewarding in the long run. You can start small and don't have to spend a lot of money and yet you can buy some very beautiful items. Many people love to take vacations to go hunting gemstones. Take the example of the US. In Michigan you can find Agate, Chlorastrolite and Hematite. And if you like to travel farther you can find opal in Opalton, Yowah, Queensland, Austalia, topaz in Mt Surprise or O'Briens Creek in Queensland, Australia or hunt in the garnet fields in Fullarton River in Queensland, Australia.
