Our Featured Gemological ArticleStarting To Collect Loose Gemstones
By Lee MacRae
Why would anyone collect items like
loose gemstones, you ask? Well to begin with they've been sought for their beauty for many centuries. And just like
natural diamonds their value increases over time. Many hobbyists love to find, collect and finish the wide variety of gemstones available today. Read long as we look at the hobby of collecting
loose gemstones.
The very first step in beginning this hobby the right way is by getting adequate knowledge about them. By taking a quick trip to the library or local bookstore you can locate all you need to know about the subject that will let you make wise purchases from the beginning.
One of the first things you look at Is gemstone color. Gemstones at the top of the ladder have colors that are close to the exact spectral color of violent, blue, green,, orange or red. Gemstone colors that are muted or on the dark side lowers the value per carat.
Gemstone cut is an important aspect to consider when evaluating gemstones. The cut has to be done correctly to reflect light properly. A gemstone with the poor cut will not reflect light in a consistent way. Color saturation, color hue and color tone will always look inconsistent.
Another factor to consider is the gemstone's clarity. This refers to the purity of the gemstone with no internal conclusions, internal particles or spots inside the crystal. Needless to say, stones with no flaws will make a gemstone very valuable.
Next comes weight and size. Except for corals and pearls, all gemstones are valued by the unit called the carat. A carat is equal to 0.2 grams. You should know however that weight and size are not always equal and gemstones. Density or specific gravity can very. Take a diamond that weighs 1.00 carats and you will see that a Sapphire or ruby of the same size would weigh 1.20 carats.
Collecting various gemstones can create an enjoyable hobby and pastime. And there are so many different types in gemstones you can collect. You can start collecting gemstones like Jasper, Opal (Girasol) or Tourmaline for instance. The varieties are nearly endless. And if you like to save money but love vacations you can go gemstone hunting and find the raw materials instead of buying them. Take the example of the United States. In Montana you'll find Agate, Sapphire, Beryl, Amethyst, Smoky Quartz, Obsidian, Tourmaline and Garnet.

There are many other common types of treatment to enhance the beauty of colored gemstones. Emeralds are often oiled and waxed to protect them and to hide fine lines that naturally occur in the stone. Some sapphires have their blue color enhanced using diffusion, a chemical process. Certain stones are treated with radiation, again mimicking the processes of nature. All these practices are standard in the jewelry industry; in fact, enhancement is so common that good quality unenhanced stones often come with a certificate stating that fact.

Gemstones Scene Updates
Gemstone Article Of The MonthThe Hobby Of Loose Gemstone Collecting
By Lee MacRae
The term gemology refers to the art, profession and science of evaluating and identifying gemstones from
natural diamonds to
loose gemstones. A number of people taken up gemology as a hobby. They collect and evaluate
loose gemstones or
loose diamonds. A number of these hobbyists start to visit various locations close by to look for raw gemstones. Some of them will even tumble or finish off the gemstones themselves. If this hobby interest you read along as we show you the things you should know to start this hobby.
First off you need to read up on each of the gemstones out there. This will help you to know what you're buying and prevent you from wasting your money. Without the proper knowledge you can make costly mistakes.
One of the first things you look at is the color of the gem. Top grade gemstones have pure colors there as close as possible in pureness to the spectral colors of violent, blue, green,, orange or red. Muted gemstone colors or are too dark lowers the value per carat.
Stone cut is the second most important value determination to consider before a purchase is made. How precise the cut is is the factor which determines how much light is reflected by the gemstone. The cut will determine the brilliance of the stone and its final value.
The clarity in a stone is an important consideration. When we talk of clarity it relates to the amount of inclusions (trace elements or large particles of other elements or minerals) that a gem has. Generally speaking, a clearer stone is obviously valued highly. To see flaws beyond with the eye can see you need a 10X gemstone loupe (gemstone clarity magnifier) or gem microscope. Most hobbyists will get a 10X jewelers were gemstone loup for viewing stamps, coins, beads as well as gems.
Next up are weight and size. Other than the corals and pearls gemstones are priced by the carat. One carat equals a 0.2 grams. Be aware however, that weight and size are not the same in gemstones. The density and specific gravity can differ in stones. Take a diamond that is 1.00 carats in weight and you will find that a similar sized sapphire or ruby would weigh 1.20 carats.
Though you may find gemstones used a lot in jewelry, loose gemstones are great for collecting. In fact, there are many attractive and interesting gems that are too fragile or too large to be used in jewelry. Look at each stone and consider it as a piece of art and value it for its unusual nature and for the craftsmanship of the artisan who shaped it. And unlike many hobbies where you have to buy everthing you can find your raw materials through field trips In the US in Missouri you can hunt for Pearl, Fluorite, Pyrite and Calcite. And in Canada you can hunt for nephrite jade in the Frances Lake area in the Yukon Territory or labradorite on the adjacent islands and coastal area of Labrador along with zircons in Sebastopol and Brudnell Townships in Renfew County, Ontario. Think of gemstone collecting for the great hobby it is.

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.

Our Latest Gemstone ArticleStarting The Hobby Of Gemstone Collecting
By Lee MacRae
Many people, young and old, say collecting various
loose gemstones or
loose diamonds is a favorite pastime. Many people have a great love of the various gemstones found around the world today. Follow along as we discuss a number of things you need to know when starting this gemstone hobby.
At the very beginning you need to learn all you can on the various gemstones available. This will help you to know what exactly you're looking for so you buy the right items. Get the answer to questions like how, where and what to buy.
The first criteria you need to evaluate is stone color. Gemstones are the most intensely colored natural material available on earth. These materials are so related to their color that they have even lent their names to specific colors. Everyone knows ruby red, emerald green, sapphire blue, aquamarine, turquoise, and jade green Gemstones are valued much higher the closer they are to the colors in the spectrum of yellow, blue, violet, green, orange and red. They drop in value when they are lighter or darker than the pure spectral color.
The cut of the stone is extremely important and is used not only to appraise diamonds along with gemstones. A good cut highlights the pure color of the stone, diminishes its inclusions, and show off its symmetry and proportions. One way of determining the excellence in the cut is to look at if it is able to reflect light on a consistent level throughout the surface of the stone. If the gemstone is cut to shallow much of the light will refract out of the gem instead of reflecting inside the gemstone. Gemstone color will be washed out.
Next to look at is the issue of gemstone clarity. Clarity refers to the internal flaws (inclusions) or the external blemishes of the gemstone under consideration. Larger flaws are visible to the naked eye with others requiring a 10X magnification.
The next factors to consider our size and weight. Save for pearls and corals, all gemstones are priced by the carat. One carat is the equivalent of 0.2 grams Be aware however, that size and weight and gemstones are not the same. Density or specific gravity can very. If you have a diamond that weighs 1.00 carats, you will find a similar sized ruby or sapphire weighs 1.20 carats.
Collecting various gemstones can create an enjoyable hobby and pastime. And there are so many different types in precious and semi precious stones that you can collect. You can start collecting gemstones like Garnet, Spinel or Natural moissanite and then try others. The choice and beauty and variety is almost endless. And if you like to save money but love vacations you can find gemstones for yourself instead of buying. Just in the United States in Michigan you can find Agate, Chlorastrolite and Hematite.
