Starting To Collect Gemstones
By Lee MacRae
Gemology is the science, art and profession of identifying and evaluating rocks known as natural diamonds or loose gemstones. A number of people taken up gemology as a hobby. They become interested in collecting and evaluating loose diamonds or loose gemstones. Some people even begin to visit various locations close by to look for rough gemstones. Some hobbyists will learn to cut or tumble the gemstones they find. If this hobby interest you follow along as we discuss the different aspects of this hobby.
The first step in starting the hobby of collecting gemstones the proper way is through the power of knowledge. By visiting a local library you can find books on the subject that will let you make wise purchases from the beginning.
The first criteria you need to evaluate is stone color. Gemstones are the most intensely colored natural materials you can find. These materials are so related to their color that they've even become associated with particular ones. You've no doubt heard about emerald green, ruby red, sapphire blue, jade green, turquoise or aquamarine. Gemstones are valued much higher the closer they are to the colors in the spectrum of red, orange, yellow, green, blue, and violet. They are valued much less the farther they are from the pure spectral color.
Gemstone cut is an important aspect to consider when buying a gemstone. The stone has to be cut correctly to reflect light properly. A gemstone with an improper cut will be muted or washed out. Color tone, saturation, and hue will never look consistent.
Gemstone clarity is the next item to consider. Clarity refers to the absence of flaws or blemishes inside the stone. Generally speaking, a clearer stone is more valuable. To determine the flaws not seen with the unaided eye you need a gemstone loupe (gemstone clarity magnifier) or gem microscope. Serious hobbyists will use an inexpensive 10X gemstone or jewelers loup for viewing their coins, beads, stamps or in our case gemstones.
Gemstones are often listed according to their size aspect since it is more uniform than carat weight. But different gemstones may have the same size but have different carat weights that result in different pricing structures. This factor comes from the difference regarding relative density or specific gravity depending upon the chemical composition and characteristic crystalline structure. Normally a one carat brilliant round diamond with standard proportions will be approximately 6.5 mm in diameter. A comparable a brilliant ruby of the same proportions in size will weigh in at 1.55 carats.
Although gems are frequently used in jewelry, they are perfectly good collectibles in their own right. In fact, there are many attractive and interesting gemstones that are too fragile or too large to be used in jewelry. Take each gemstone and consider it as a piece of art and value it for its unique nature and vibrant colors. And unlike many hobbies where you have to buy everthing you can actually go hunting for raw gemstones in the field. In the US in Hawaii you can find Peridot and Coral. And in Canada you can hunt for nephrite jade in Cry Lake, British Columbia or blue spinel from Daillebout, Quebec along with amethyst from Nova Scotia. Think of gemstone collecting for the great hobby it is.

Many gemstones will undergo some kind of treatment between the time they are
mined and the time they reach you. These treatments are carried out in order to
improve the appearance of the stone (color or clarity). Treatments include
exposure to very high temperatures, irradiation, heat or irradiation combined
with another chemical (e.g. titanium), oiling, and waxing. Treated gemstones
are not considered less valuable as long as the treatment is considered
�permanent� by relevant gemological organizations. That means that the
treatment will not �wear off� with time. In some kinds of gemstones, treatments
are so common that it is nearly impossible to find an untreated one. Rubies are
an example of this. Other gemstones could not exist without treatments, e.g.
Mystic topaz.

The Hobby Of Loose Gemstone Collecting
By Lee MacRae
Why would someone go to the trouble of collect loose gemstones? Well for one thing they've been sought for their beauty for many centuries. And like their higher counterpart, natural diamonds their value increases over time. Many people love to find, collect and finish the nearly 150 types of gemstones found today. This article will look at the hobby of collecting loose gemstones.
The very first step in becoming a gemstone collector the smart way is by getting adequate knowledge about them. By taking a look in your local bookstore you can find books on the subject that will make you an informed buyer.
Number one to look at is the color of the gem. Top grade gemstones have colors that are close to the purest spectral colors of orange, green, yellow, Violet or blue. Muted gemstone colors or are too dark lowers the value per carat.
Cut is one of the all-important 4Cs and factors into appraisal of diamonds but along with your gemstones. A precision cut gemstone showcases the pure color of the stone, diminish any inclusions, and exhibits good overall symmetry and proportion. One excellent way to determine the excellence of its cut is to check if it is able to reflect light on a consistent level throughout the surface of the stone. If the gemstone is cut to shallow most of this light were refracted away instead of reflecting inside the gemstone. Gem color appears washed out.
Next up is gemstone clarity. Clarity is the term that refers to internal flaws (inclusions) or the external blemishes of a stone being considered. Normally large flaws can be seen with the unaided eye with others requiring a 10X magnification.
You will note that gemstones are categorized according to their size aspect since it is more uniform than carat weight. But two different gemstones may have the same size but different carat weights and consequently, different in prices as well. This is due to the difference in specific gravity or relative density and depends on the materials chemical composition and crystalline structure. For example, a one carat round diamond 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.
Though you may find gemstones used a lot in jewelry, they are perfectly good collectibles in their own right.

So You Want To Collect Loose Gemstones

The term gemology refers to the profession, science, and even art of evaluating and identifying gemstones from loose gemstones to natural diamonds. Many people take up gemology more as a hobby. They become interested in making a collection of items like loose gemstone or natural diamonds. You'll even find some that like to travel to different areas close by or even taking a trip to other countries to look for rough 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 various factors in gemstone collecting.

Color is a subjective idea but a very important part in the value of the stone. The closer the color comes to its pure spectral color the more highly prized it is. Traditionally, these specter colors are yellow, blue, Violet, green, orange and red. Colors that tend to be paler or darker diminish the value of the stone.
The way a stone is cut is the second most important value determination to look at before a purchase is made. The precision of cut will determine how much light the gemstone stone will reflect. The cut will factor highly in the brilliance of the stone and its final value.
A third consideration is the clarity of the stone under consideration. This is talking about the purity of the stone or the absence of internal inclusions, spots, or particles within the crystal structure. Obviously, stones with a lack of flaws would make the gemstone highly valuable.
Gemstones are often categorized according to their size aspect because of being more uniform than carat weight. But two different gemstones may have the same size but differ in carat weights and as a result different in prices as well. This is due to the nature of gemstone 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.

Hints About natural blue diamonds
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.

Color is a very important part in evaluating a gemstone. The closer the color comes to its purer spectral value the more valuable it is. Traditional spectral colors include violent, blue, green,, orange and red. Colors that tend to be darker or paler tend to be less valued.
The cut of the stone is extremely important and factors into appraisal of diamonds but gemstones as well. An excellent cut will highlight the pure color of the stone, diminishes its inclusions, and highlight the proportions and symmetry of the stone. One excellent way to determine the excellence in gemstone cut is to consider how well and consistent it reflects light over its entire surface. But if a gem is cut too shallow, most of this light were refracted away instead of reflecting inside. That will make the gem seem washed out and windowed.
The next factor to look at is the clarity of the stone under consideration. This is talking about the gemstones purity or the lack of internal inclusions, particles or spots within the crystal. Needless to say, stones with no flaws would make the gemstone highly valuable.

The Diamond is the birthstone of April and the anniversary gemstone for the 10th
and 60th years of marriage. Diamonds were discovered in India in 500 B.C., and
the name "diamond" comes from the Greek word "Adamas" which means unconquerable
- suggesting the eternity of love. Since ancient Greece, diamonds and diamond
jewelry have been the traditional symbol of love, and the ancients believed they
were hardened dew drops, splinters from the stars or crystallized lightning. A
diamond is the hardest substance known to humankind, and is made of a
crystallized carbon that has unique powers of light reflection. Since diamonds
are composed of a single element, they are the purest of all gemstones.
