Featured Gemological ArticleThe Hobby Of Gemstone Collecting
By Lee MacRae
Many people today say collecting
loose gemstones or
loose diamonds is their favorite hobby. They simply love the beauty and the colors of the wide array of gemstones found around the world today. This article will look at a number of factors you should understand in starting in this interesting hobby.
The first step in beginning this hobby the right way is by acquiring knowledge about them. By taking a look in your local bookstore you can find everything you need to know that will help you to know exactly what you should do.
Color is a very important part in the value of the stone. The closer a color is to its purer spectral value the more highly prized it is. Traditionally, these specter colors are yellow, blue, Violet, green, orange and red. Colors that tend to be darker or paler tend to be less valued.
Gemstone cut is an important aspect to consider when evaluating gemstones. The stone has to be cut with precision to reflect the light properly. A gemstone with an improper cut will be muted or washed out. The color hue, color tone and saturation will be inconsistent.
The next factor to consider is the gemstone's clarity. This is talking about the purity of the gemstone or the absence of internal inclusions, spots, or particles within the crystal. Without a doubt, zero flaws will make a gemstone very valuable.
You will note that gemstones are categorized according to their size aspect because it is more uniform than carat weight. But two 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 specific gravity or relative density and depends on the materials chemical composition and crystal structure type A one carat round brilliant diamond, for example of typical proportions will be approximately 6.5 mm in diameter. A ruby that is the same size will weigh in at 1.55 carats instead.
Although gemstones are normally used for jewelry, they are perfectly good collectibles in their own right. Actually there are many interesting and attractive gemstones who that are too fragile or too large to be used in jewelry. Take each loose gemstone and 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 find your raw materials through field trips In the US in California you can find Agate, Benitoite, Californite, Diamond, Citrine, Tourmaline, Abalone Pearl, Kunzite, Chrysopras And in Canada you can find nephrite jade in Cry Lake, British Columbia or labradorite on the adjacent islands and coastal area of Labrador as well as ammolite from Lethbridge, Alberta. Think of gemstone collecting for the great hobby it is.

Tips On quality loose diamonds
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.

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.
