More Info On small loose diamond
The GIA recently released a new cut grading system and it appears they have
finally conquered this beast. Rather than calculating how close a cut came to an
�ideal� set of proportions, the new system is based on how the individual
elements combine to affect the appearance of a diamond. In addition, they were
able to install some flexibility in the system to allow for personal preferences
, with table size being a prime example.

Latest Gemological ArticleHow To Collect Loose Gemstones
By Lee MacRae
Gemology is a term referring to the art, profession and science of evaluating and identifying gemstones from
loose gemstones to
natural diamonds. Many people take up gemology more as a hobby. They become interested in collecting and evaluating
loose diamonds or
loose gemstones. You'll even find some that like to travel to different areas to look for raw gemstones. Some hobbyists will learn to cut or tumble the gemstones they find. If this hobby interest you then read along as we show you the various factors in gemstone collecting.
The first thing you need to do is to visit the library and get some books. You want to understand as much as possible about your new hobby. The more you understand about each kind of gemstone the wiser will be your purchases. You'll know exactly what to look for in a quality stone.
To start with, an important aspect in gemstone evaluation is color. Gemstones are the most intensely colored natural material available on earth. These materials are so related to their color that they've even had their names combined with associated colors. Everyone knows ruby red, emerald green, sapphire blue, aquamarine, turquoise, and jade green Gemstones will have a higher value when they are equal in color to the spectral colors of orange, green, yellow, violet and blue. They are valued much less when they are lighter or darker than the pure spectral color.
The cut of the gemstone is an important aspect to consider in evaluating gemstones. The gemstone must be cut correctly to reflect light properly. A gemstone with the poor cut can't reflect the light consistently over its surface. The color hue, color tone and saturation will never look consistent.
The next factor to look at is the stone's clarity. This is talking about the gemstones purity or the lack of internal inclusions, internal particles or spots within the crystal structure. Obviously, stones with a lack of flaws will make a gemstone very valuable.
Gemstones are often categorized according to their size aspect because of being more uniform than carat weight. But two different gemstones may be of the same size but have different carat weights that result in different prices as well. This is due to the difference of relative density or specific gravity depending upon the chemical composition and crystalline structure. Normally a one carat brilliant round diamond with standard proportions will be approximately 6.5 mm in diameter. A comparable round brilliant ruby of the same size and proportions will weigh approximately 1.55 carats.
Getting involved in collecting gemstones can be very enjoyable and rewarding in the long run. It doesn't have to be very expensive and yet you can buy some very beautiful items. Many people love to set aside vacation or weekend time to go looking for gemstones. For example in Florida you can find Chalcedony and Conch Pearl. And if you like to travel farther you can find opal at Lightning Ridge in NSW, Austalia, topaz in Mt Surprise or O'Briens Creek in Queensland, Australia or check out the Moonstone regions in Moonstone Hill, Queensland, Australia.

Two Afrikaner brothers owned a farm where the Orange and Vaal rivers join.
Johannes Nicholas de Beer and Diederik Arnoldus de Beer had diamonds discovered
on their property. They were in no position to protect the property from diamond
hunters and predators so they sold it for 6300 pounds to investors Cecil Rhodes
and Charles Rudd. Two mines were actually found on the property located in the
Kimberly region. One mine was named after the original owners of the property,
and the other one was named after the area. The De Beers and Kimberly mines were

Consolidated Mines Limited. It couldn't have happened at a better time.
