Starting To Collect Gemstones
By Lee MacRae
Why collect loose gemstones you ask? For many people it's because they are very beautiful items. And just like natural diamonds they can become extremely valuable over the years. Many in this hobby love to collect and show case each and every one of the 150 varieties available. Read long as we discuss the hobby of loose gemstone collecting.
The first thing you need to do in becoming a gemstone collector the proper way is by acquiring knowledge about them. By visiting a local library you can find books on the subject that will make you an informed buyer.
The first item to consider should be the color of the stone. You'll want the stone to be as close as possible to the pure colors of the spectrum. The spectral colors are blue, green, yellow, orange, red and violet. In general terms, the prices of very dark are very pale precious and semi precious stones are lower.
The cut of the gemstone is the second most important value determination to take a look at. How precise the cut is is the factor that determines the amount of light the stone will reflect. The cut will ultimately determine the stones brilliance and how much it will be valued.
The clarity of a gemstone is an important consideration. Clarity refers to the amount of inclusions (trace elements or large particles of other elements or minerals) that a gem has. A perfect gemstone is more valuable. To see flaws beyond with the eye can see requires a 10X gemstone clarity magnifier or gem microscope. Many hobbyists will buy a 10X jewelers were gemstone loup for viewing their coins, beads, stamps or in our case gemstones.
You will note that gemstones are categorized according to their size criteria since it is more uniform than carat weight. But different gemstones may be of the same size but differ in carat weights and as a result different in prices as well. This is due to the difference regarding specific gravity depending upon the chemical composition and crystal structure type Normally a one carat brilliant round diamond of typical proportions will be approximately 6.5 mm in diameter. A comparable round brilliant ruby of the same size and proportions will weigh in at 1.55 carats.
Getting involved in collecting gemstones can give you an enjoyable pastime and also rewarding in the long run. You don't need to spend a lot of money and yet you can buy some very beautiful items. Many people love to set aside vacation or weekend time to go hunting gemstones. Take the example of the United States. In Arizona you can find Agatized wood (Petrified wood), Azur-Malachite, Turquoise, Garnet, Peridot, Jasper and Moissanite Or you can take the time to travel and find opal at Lightning Ridge in NSW, Austalia, topaz in Torrington, New South Wales, Australia or hunt the sapphire fields in Anakie, Rubyvale, Sapphire, Glenalva, The Willows, Inverell or Glen Innes in Queensland, Austalia.

Blue topaz was once extremely rare; however, now it is one of the most available color topaz on the market. Most topaz found in nature is colorless. To get their blue color, a colorless topaz goes through a process called �irradiation� which is used to heat and color the stone blue. They can be mistaken for the more expensive aquamarine. Most blue topaz are mined in Brazil, Sri Lanka and Australia. Do not expose blue topaz to direct sunlight or extreme or prolonged heat which can cause damage or fading. It ranks 8 on the Mohs Scale of Hardness. It is the shared birthstone for the month of December with turquoise.

Brilliance is the amount of light reflected from the crown facets of a facet-cut gemstone. It is a combination of the light reflected back out of the stone and the light reflected directly from the facet surfaces. Two factors critical in achieving maximum brilliance are the angle of the pavilion facets and the degree of polish on the facet surface (lustre). The table facet of a diamonds is cut to various sizes depending on the desire for more brilliance and less fire(dispersion), where a larger table is used. Or more fire and less brillinace, where a smaller table is used. A good balance is obtained by cutting to ideal proportions. The pavilion facet angles are not only critical in determining the amount of brilliance, shallow angles may result in creating a 'window' in the stone; an area of the stone that can be seen through. Deep angles result in dark areas in the stone, termed extinction. Brilliance is lost in both situations.
