Collecting Prescious And Semi-Prescious Stones


By Lee MacRae


Many people, young and old, say collecting semi-precious and precious gemstones like loose diamonds or loose gemstones is a passionate hobby. They simply love the beauty and the colors of the wide array of gemstones you can find just about everywhere in the world. Follow along as we discuss a number of things you need to know when starting to collect varieties of gemstones yourself.


Right at the start you need to learn all you can on the wide variety of stones available. You'll find it very helpful to know what exactly you're looking for so you buy the right items. A knowledgeable buyer is a wise one.


First, color is a major part in evaluating a gemstone. The closer the color comes to its purer spectral value the more highly prized it is. Remember that the spectral colors include red, orange, yellow, green, blue, and violet. Colors that are darker or palerthan a pure color are considered a lower value.



Gemstone cut is very important and is used not only to appraise diamonds but gemstones in general as well. A precision cut will highlight the gemstone's color, lessen any inclusions and exhibits good overall symmetry and proportion. One way to determine the precision in gemstone cut is to consider how consistent and well, it reflects the light over its entire surface. But if a gem is cut too shallow, most of this light were refracted away rather than reflecting internally. Gem color appears washed out.


The next factor to consider is the clarity. This is talking about the gemstones purity with no internal conclusions, spots, or particles within the crystal structure. Obviously, stones with a lack of flaws are hard to find and make your stones very valuable.


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


Taking up the hobby of gemstones can become an enjoyable pastime and also rewarding in the long run. You don't need to spend a lot of money and yet you can end up with some very beautiful stones. Many people loved to spend weekends to go hunting for raw gemstones. Take the example of the US. In Alabama you can find Beryl, blue and yellow; Smoky Quartz and Hematite. Or you can take the time to travel and find opal in Opalton, Yowah, Queensland, Austalia, topaz in Killiecrankie, Tasmania or hunt in the garnet fields in Fullarton River in Queensland, Australia.
