Featured Gemstone ArticleHow To Collect Loose Gemstones
By Lee MacRae
Gemology is the science, art and profession of identifying and evaluating rocks known as
natural diamonds or
loose gemstones. Many people take up gemology more as a hobby. They become interested in collecting and evaluating items like
loose gemstone or
natural diamonds. You'll even find some that like to visit various locations close by or even in other countries to hunt for raw or rough gemstones. Some of them will even tumble or finish off the gemstones themselves. If this sounds like a hobby you would like to get involved in read along as this article discusses the things you should know to start this hobby.
The first thing you need to do is to get some books from the library or bookstore. You want to learn as much as you possibly can about the subject of gemstones. The more you learn about each kind of gemstone the better off you'll be. With adequate knowledge you are less likely to be fooled.
To start with, an important aspect in gemstone evaluation is color. Gemstones are the most intensely colored natural materials you can find. Gemstones are so related to color that they have even lent their names to specific colors. You've no doubt heard about emerald green, ruby red, sapphire blue, jade green, turquoise or aquamarine. Gemstones are valued much higher when they equal the colors in the spectrum of violet, blue, green,, orange and red. They are valued much less the farther they are from the spectral color.
Cut is one of the all-important 4Cs and factors into appraisal of diamonds but gemstones in general as well. A good cut showcases the natural color of the gemstone, diminishes its inclusions, and exhibits good overall symmetry and proportion. One way of determining the excellence in gemstone cut is to consider how consistent and well, it reflects the light throughout its surface. But if a gem is cut too shallow, most of this light were refracted away instead of reflecting inside. Gemstone color will be washed out.
The clarity in a stone is our next factor. 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. A flawless gemstone is obviously valued highly. To determine the flaws not seen with the unaided eye you need a gemstone loupe (gemstone clarity magnifier) or gem microscope. Serious hobbyists will buy a jewelers diamond gemstone loupe 10X for viewing their coins, beads, stamps or in our case gemstones.
Next comes size and weight. Except for corals and pearls, all gemstones are valued by the unit called the carat. One carat is the equivalent of 0.2 grams However you should know weight and size are not the same in gemstones. Density or specific gravity can vary in gemstones. If you have a diamond that weighs 1.00 carats, you will find a Sapphire or ruby of the same size would weigh 1.20 carats.
Taking up the collecting of loose gemstones can create an enjoyable hobby and pastime. And there is such a variety in gemstones you can collect. You can start collecting gemstones like Jade [jadeite and nephrite], Chalcedony (bloodstone) or Iolite for example. The varieties are nearly endless. And if you like to save money but love vacations you can go hunting for raw gemstones. Take the example of the United States. In Pennsylvania you can find Amethyst, Almandite Garnet and Pyrope Garnet, Beryl, Sunstone and Moonstone.

Our Latest Gemstone ArticleCollecting Prescious And Semi-Prescious Stones
By Lee MacRae
Many people, young and old, say collecting semi-precious and precious gemstones like
loose diamonds or
loose gemstones is a passionate hobby. Many people have a great love of the various gemstones you can find just about everywhere in the world. This article will look at a number of factors you should understand when starting this interesting gemstone hobby.
The first thing you need to do is to get yourself some books on gemstones. You want to learn as much as possible about your new hobby. The more you learn about gemstones the better off you'll be. You will know exactly what you are looking at.
The first criteria you need to evaluate is stone color. Gemstones are the most intensely colored natural materials you can find. Gemstones are so related to color that they've even become associated with particular ones. Without a doubt you will recognize sapphire blue, ruby red, jade green, aquamarine, emerald green or turquoise. Gemstones will have a higher value the closer they are to the colors in the spectrum of orange, green, yellow, violet and blue. They drop in value the farther they are from the natural color.
How the gemstone has been cut is the second most important factor to consider before buying. The precision of cut determines the amount of light the stone will reflect. It will ultimately determine the brilliance of the stone and how much it will be valued.
Next to look at is the aspect of gemstone clarity. Clarity refers to the internal flaws (inclusions) or the external blemishes of a stone. Normally large flaws you can usually see with your naked eye with others needing to be magnified 10X
Next item to look at is the duo of weight and size. Due to the fact gemstones vary and specific gravity or density. Size and weight are not necessarily equal from stone to stone. If you have a diamond that weighs 1.00 carats a ruby of equal size would weigh 1.20 carats. An emerald stone would be about 0.95 carats and an Alexandrite gemstone would be about 1.23 carats.
Taking up the collecting of loose gemstones can be very rewarding hobby. And there is such a variety when it comes to gemstones. You could try collecting Alexandrite and other varieties of chrysoberyl, Pyrite or Tourmaline for instance. The varieties are nearly endless. And if money is tight you can go gemstone hunting and find the raw materials instead of buying them. Just in the United States in Wyoming you can find Agate (including Moss Agate), Jade, Ruby, Jasper, Bloodstone as well as Star Sapphire.

The most common method of finishing a gemstone in fine jewelry is cutting facets
. Faceting allows for the most sparkle and light reflection. Simply put, you can
tell a good cut (faceted stone) by how well it sparkles. A properly cut stone
has its facets at particular angles to reflect the most light possible. This is
because cutting a stone at the best reflective angles often means reducing the
size and weight of the stone.

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.
