Our Featured Gemological WriterStarting To Collect Loose Gemstones
By Lee MacRae
Gemology is a term referring to the art, profession and science of evaluating and identifying rocks known as
natural diamonds or
loose gemstones. A number of people taken up gemology as a passionate hobby. They become very interested in starting to collect
loose diamonds or
loose gemstones. A number of these hobbyists start to visit various locations close by to look for raw gemstones. Some hobbyists will learn to cut or tumble the gemstones they find. If you have an interest in this hobby read along as we reveal the in and outs of gemstone collecting.
The very first step in becoming a gemstone collector the proper way is by getting adequate knowledge about them. By taking a quick trip to the library or local bookstore you can find everything you need to know that will let you make wise purchases from the beginning.
First on your list to take into account is stone color. You want the stone to be as close in color as possible to the pure spectral colors. This means red, orange, yellow, green, blue, and violet. The prices of very dark are very pale precious and semi precious stones are lower than the vibrant colors.
Gemstone cut is very important and factors highly into the appraisal of not only diamonds along with gemstones. A precision cut gemstone showcases the gemstone's color, diminishes its inclusions, and exhibits good overall symmetry and proportion. One excellent way to determine the excellence regarding the cut is how evenly it reflects light throughout the surface of the stone. If the gemstone is cut to shallow much of the light will refract out of the gem rather than reflecting internally. Gemstone color will be washed out.
Gemstone clarity is an important consideration. Clarity refers to the absence of flaws or blemishes inside the stone. The gemstone without flaws is more valuable. To determine the flaws not seen with the unaided eye requires a 10X gemstone loupe or gemstone microscope. Serious hobbyists will get a 10X jewelers were gemstone loup for examining coins, stamps and of course gemstones.
Gemstones are often listed according to their size because it is more uniform than carat weight. But two different gemstones may be of the same size but differ in carat weights and as a result different in prices as well. This factor comes from the difference of specific gravity depending upon the chemical composition and crystalline structure. For example, a one carat round diamond with normal proportions is approximately 6.5 mm around. A comparable round brilliant ruby of the same size and proportions will weigh in at 1.55 carats.
Though you may find gemstones used a lot in jewelry, they are a great hobby and pastime as well. In fact, there are many attractive and interesting gems that are simply too big and fragile for use in jewelry. Here's a suggestion -- don't think of a gem as a component of jewelry; think of it as a piece of art, a miniature sculpture to be treasured for its unusual nature and for the craftsmanship of the artisan who shaped it. And in this hobby you don't have to always lay out cash because you can use vacation time to actually hunt for raw gemstones in stead of buying. In the US in Colorado you can find Beryl, Aquamarine, Phenacite, Garnet, Amethyst, Agate, Citrine, Pyrite, Rose Quartzcomma

Topaz can be found in streams, rivers and in gravel deposits. It is found mainly
in gem pegmatites where the presence of fluorine can be found. Flourine provides
a rich environment for the stones to grow into very large crystals. In fact,
without the presence of Flourine topaz would not exist. Topaz crystallizes
orthorhombically and develops columns with square and diamond shapes planes with
multisurfaced heads. Topaz can also be found in cracks and cavities where a
combination of Flourine and silica and alumina which was released by very hot
temperatures caused the gems to form. Chromium Oxide is what provides its
beautiful color.
