Collecting Gemstones


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 love the colors and the beauty of the wide array of gemstones found worldwide today. Read long as we look at a number of factors you should understand in starting in this hobby.


Right at the start you need to read up on the wide variety of stones available. This will help you to know what exactly you're looking for so you buy the right items. This will help you make informed decisions.


The first item to consider should be the color of the gemstone. You'll want the stone to be as close in color as possible to the pure colors of the spectrum. The spectral colors are red, orange, yellow, green, blue, and violet. The prices of very dark are very pale precious and semi precious stones are lower in value.


The cut of a stone is the next factor to consider. How precise the cut is is the factor that determines the amount of light the stone will reflect. It will ultimately determine the brilliance of the stone and how much it will be valued.


The clarity in a stone is our next factor. Gemstone clarity relates to the amount of inclusions (trace elements or large particles of other elements or minerals) that a gem has. A flawless gemstone 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 viewing stamps, coins, beads as well as gems.


Gemstones are often categorized according to size because it is more uniform than carat weight. But different gemstones may be the same size but have different carat weights that result in different prices as well. This is due to gemstone difference regarding specific gravity or relative density and depends on the materials chemical composition and characteristic crystalline structure. For example, a one carat round diamond with standard proportions will be approximately 6.5 mm in diameter. A comparable a brilliant ruby of the same proportions in size will weigh in at 1.55 carats.


Collecting various gemstones can be very rewarding hobby. And there is such a variety in gemstones you can collect. You can collect gemstones like Malachite, Chalcedony (bloodstone) or Variscite and then try others. The opportunities are seemingly endless. And if money is tight you can go gemstone hunting and find the raw materials instead of buying them. Take the example of the US. In New York you can find Beryl, Brown Tourmaline, Rose Quartz as well as Fresh Water Pearl.
