Collecting Prescious And Semi-Prescious Stones
By Lee MacRae
Why collect loose gemstones you ask? Well to begin with gemstones are extremely beautiful. And just like natural diamonds their value increases over time. Many hobbyists love to collect and work with the wide variety of gemstones available today. This article will examine the loose gemstones hobby.
To begin with your first priority is to get some books from the library or bookstore. You want to know everything there is to know about the subject of gemstones. The more you learn about gemstones the better off you'll be. You'll know exactly what to look for in a quality stone.
The first item to take into account will be gemstone color. You want the gemstone to be as close in color as possible to the pure colors of the spectrum. This means red, orange, yellow, green, blue, and violet. Generally, the prices very pale or very dark precious and semi precious gemstones are lower in value.
Gemstone cut is the second most important factor to look at. The preciseness of the cut will determine how much light is reflected by the gemstone. The cut will determine the brilliance of the stone and how much it will be valued.
Next up is the aspect of gemstone clarity. Clarity refers to the the internal conclusions or flaws of a stone being considered. Larger flaws can be seen with the unaided eye with others needing to be magnified 10X
Gemstones are often categorized according to their size aspect because of being more uniform than carat weight. But different gemstones may be the same size but have different carat weights that result in different pricing structures. This is due to the difference of relative density or specific gravity and depends on the materials chemical composition and characteristic crystalline structure. A one carat round brilliant diamond, for example of typical proportions will be approximately 6.5 mm in diameter. A comparable a brilliant ruby of the same proportions in size will weigh approximately 1.55 carats.
Collecting gemstones as a hobby can be very enjoyable and could be rewarding as well over time. It doesn't have to be very expensive and yet you can build a very exquisite collection. Many people love to set aside vacation or weekend time to go hunting gemstones. For example in New Mexico you'll find Turquoise, Garnet, Peridot, Rock Crystal and Obsidian Or ou can take a longer vacation and find opal at Lightning Ridge in NSW, Austalia, topaz in Beechworth, Victoria or hunt specimens the quartz regions in Wave Hill in the Northern Territory of Australia.

Topaz is a very large stone. One giant gem at the Viennese Historical museum is
reputed to weigh 585,000 carats. The rarest topaz is the Imperial Topaz and pink
topaz. Pakistan is the only place today where rose-red tinted topaz can be found
today. All other pink topazes get their color from heat treatments of up to 475?
C. Imperial topaz is has a yellow tint to it while other members of the topaz
family can be completely colorless. Some of the most beautiful examples of topaz
are the famous blue topaz which can have colorful ranges starting with light
blue stones. The very deep blue topaz is artificially produced by heating and
irridation processes. One of the most interesting characteristics about topaz is
that it bleaches in daylight and then renews itself as the light subsides. The
color changes occur because of natural heating and irridation.

Emeralds are hard but are sensitive and prey to flaws or inclusions. They
require a lot more care than most other gemstones. The flaws occur through the
trials imposed by nature, and sometimes the engineering process developed by man
. The identification of fissures, however, does serve a useful purpose. The
flaws help to weed out artificial emeralds from the real ones. Inclusions
actually prove an emeralds authenticity. Refraction and density of the stones
vary from the location where they are found. Emeralds are found buried in their
parent rock.
