Collecting Gemstones
By Lee MacRae
For many people collecting various loose gemstones or loose diamonds is a favorite pastime. They simply love the beauty and the colors Of the assorted number of gemstones you can find just about everywhere in the world. This article will discuss a number of things you need to know in starting in this interesting hobby.
To begin with 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 chief thing you need 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 orange, red, violet, green, yellow, and blue. The prices of very dark are very pale precious and semi precious gemstones are less per carat.
The cut of a gemstonestone is the second most important value determination 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. Clarity refers 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.
You will note that gemstones are categorized according to their size criteria since it is more uniform than carat weight. But two different gemstones may be of the same size but different carat weights and consequently, different in prices as well. This is due to the nature of gemstone difference of specific gravity or relative density depending upon 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 ruby that is the same 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 Lapis lazuli, Chalcedony (bloodstone) or Turquoise 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 Hampshire you can rock hunt for Beryl, Rock Crystal and Garnet.

The topaz has superb qualities of color, clarity and hardness. Its. hardness
allows it to be easily polished because it contains an innate smoothness. The
smoothness and slipperiness of topaz is one of the ways it is identified along
with the brilliancy of color. It comes in all different shades of yellow, blue,
brown and rose reds. Most deep blue hues are produced artificially by heat and
irridation. Citrine is sometimes mistaken for topaz. The more intense colors of
topaz is what usually sets it apart from the lighter citrine colors. However,
there is a test known as the "methylene iodide test" that can make a final
determination. A stone is place in the solution, and a citrine gem will float
while the topaz will sink to the bottom. While hardness is a definite prime
attribute, topaz has a real disadvantage with its. basal cleavage. This makes
the stone very sensitive to sharp blows so artisans and miners have to handle it
very carefully.
