Starting To Collect Gemstones

By Lee MacRae

Gemology is the art, profession and science of evaluating and identifying gemstones from loose gemstones to natural diamonds. A number of people taken up gemology as a hobby. They become interested in collecting loose diamonds or loose gemstones. A number of these hobbyists start to visit different areas nearby or in some cases other countries to hunt for raw or rough gemstones. Some even tumble or learn to cut their own gemstones. If this sounds like a hobby you would like to get involved in follow along as we discuss the different aspects of this hobby.

To begin with you'll need the knowledge on each of the gemstones out there. You'll find it very helpful to know the properties of each stone and prevent you from making mistakes. Without the proper knowledge you can make costly mistakes.

Number one to look at Is gemstone color. Top grade gemstones have pure colors there as close as possible in pureness to the spectral colors of red, orange, yellow, green, blue or violet. Muted gemstone colors or are too dark can lower the value.

Gemstone cut is the next factor to consider before a purchase is made. The precision of the cut will determine how much light is reflected by the gemstone. It will fully factor highly in the brilliance of the stone and how much it will be valued.

Next up is the clarity of the gemstone. Clarity is the term that refers to internal flaws (inclusions) or the external blemishes of a stone. Larger flaws can easily be seen with the naked eye while others need a 10X magnification.

You will note that gemstones are categorized according to size because of being 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 factor comes from the difference in specific gravity and depends on the materials chemical composition and characteristic crystalline structure. Normally a one carat brilliant round diamond with standard proportions will be approximately 6.5 mm in diameter. A ruby that is the same size will weigh in at 1.55 carats instead.

Collecting gemstones as a hobby can be very enjoyable and could be rewarding as well over time. You can start small and don't have to spend a lot of money and yet you can end up with some very beautiful stones. Many people love to set aside vacation or weekend time to go looking for gemstones. Take the example of the United States. In Missouri you can hunt for Pearl, Fluorite, Pyrite and Calcite. 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 check out the quartz regions in Mt Hope or Inverell, New South Wales.

When it comes to gemstones, size matters. All else being equal, the bigger the
stone, the more valuable it is. In wholesale gem trading, gems are often priced
per carat. It would make sense therefore that the more carats, the more its
worth. However, it doesn�t stop there. An additional factor in the value is
the rarity of large stones. This means that the larger the stone, the higher
the price per carat. For example, a 1 carat ruby with a nice color and cut
might cost $700. But a 5 carat ruby of similar cut and color will not cost $
3500 (5 X $700); it might cost $10,000. This is because it is very rare to find
a ruby that is 5 carats. The effect that size has on price and value is
determined by how rare large stones are. For example, very large pieces of
amethyst and topaz are relatively easy to find meaning that the price of large
stones is not exponentially higher.
