Collecting Prescious And Semi-Prescious Gemstones
By Lee MacRae
The term gemology refers to the profession, science, and even art of evaluating and identifying rocks known as natural diamonds or loose gemstones. A number of people taken up this profession more as a hobby. They become interested in collecting loose diamonds or loose gemstones. You'll even find some that like to travel to various neghbourhood locations to look for rough gemstones. Some hobbyists will learn to cut or tumble the gemstones they find. If this hobby interest you then follow along as we show you the in and outs of gemstone collecting.
The first step in beginning this hobby the intelligent way is by acquiring knowledge about them. By visiting a local library you can find everything you need to know that will help you to know exactly what you should do.
First on the list to evaluate is gemstone color. It is a fact that gemstones are the most intensely colored naturally occurring materials you can find. 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 are valued much higher the closer they are to the colors in the spectrum of yellow, blue, violet, green, orange and red. They are valued much less the farther they are from the pure spectral color.
Gemstone cut is very important and factors into appraisal of diamonds but gemstones in general as well. An excellent cut will showcase the gemstone's color, diminish any inclusions, and show off its symmetry and proportions. One way to determine the precision regarding the cut of the gemstone is how consistent and well, it reflects the light over its entire surface. If the gemstone is cut to shallow much of the light will refract out of the gem instead of reflecting inside. That will make the gem seem washed out and windowed.
The next factor to consider is the clarity of the stone under consideration. This means the purity of the stone or the lack of internal inclusions, particles or spots inside the crystal. Needless to say, stones with no flaws are hard to find and make your stones very valuable.
Gemstones are often categorized according to their size because of being more uniform than carat weight. But different gemstones may be of the same size but have different carat weights that result in different in prices as well. This is due to the nature of gemstone difference of specific gravity or relative density and depends on the materials chemical composition and crystal structure type Normally a one carat brilliant round diamond of typical proportions will be approximately 6.5 mm in diameter. A comparable round brilliant ruby of the same size and proportions will weigh in at 1.55 carats instead.
Although gemstones are normally used for jewelry, loose gemstones are great for collecting. In fact, there are many attractive and interesting gemstones that are simply too big and fragile for use in jewelry. Take each loose gemstone and think of it as a piece of art, a miniature sculpture to be treasured for its unique nature and vibrant colors. 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 United States in Virginia you can find Amethyst, Garnet, Beryl and Moonstone. And in Canada you can find rhodonite at various locations in British Columbia or amazonite (microcline) near Lac St-Jean, Quebec along with black spinel in Burgess and bathhurst Townships in Ontario. Take up gemstone collecting and you won't regret it.

So You Want To Collect Gemstones
By Lee MacRae
Why would anyone collect items like loose gemstones, you ask? Well to begin with they are very beautiful items. And like their higher counterpart, natural diamonds they can appreciate in value over time. Many in this hobby love to collect and work with the nearly 150 types of gemstones found today. This article will examine the loose gemstones hobby.
The first thing you need to do is to get yourself some books on gemstones. You want to understand as much as you possibly can about the subject of gemstones. The more you learn about the hobby of gemstones the less likely you are to make a mistake. You will know exactly what to look for.
One of the first things you look at is the color of the gemstone. Gemstones at the top of the ladder have pure colors there as close as possible in pureness to the spectral colors of violent, blue, green,, orange or red. Gemstone colors that are muted or on the dark side can lower the value.
Cut is one of the all-important 4Cs and is used not only to appraise diamonds but gemstones in general as well. A good cut highlights the pure color of the stone, lessen any inclusions and exhibits good overall symmetry and proportion. One excellent method to determine the precision in the cut of the stone is to consider how well it reflects light on a consistent basis throughout its surface. But if a gem is cut too shallow, most of the light will refract out instead of reflecting internally. The gem appears washed out.
Next to look at is the issue of gemstone clarity. Clarity is the term that refers to the external blemishes or the internal conclusions or flaws of the gemstone under consideration. Larger flaws you can usually see with your naked eye with the others needing a 10X magnification.
You will often find that gemstones are often listed 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 nature of gemstone difference regarding specific gravity depending upon the materials chemical composition and crystalline structure. A one carat round brilliant diamond, for example 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.
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 just too big or fragile to be used for jewelry. Look at 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 unlike many hobbies where you have to buy everthing you can find your raw materials through field trips In the US in Idaho you'll find Garnet, Opal, Agate, Obsidian and Sapphire. And in Canada you can find rhodonite at various locations in British Columbia or labradorite on Tabor Island, as well as hessonite garnet in Asbestos, Quebec. Take up gemstone collecting and you won't regret it.

Collecting Prescious And Semi-Prescious Stones
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 like their higher counterpart, natural diamonds they can appreciate in value over time. Many in this hobby love to find, collect and finish the wide variety of gemstones available today. Follow along as we examine the loose gemstones hobby.
To begin with your first priority is to get yourself some reading material. You want to learn everything there is to know about precious and semiprecious gemstones. The more you know about each kind of gemstone the better off you'll be. You'll know exactly what to look for in a quality stone.
The chief thing you need to take into account is the color of the stone. You want the gemstone that is as close as possible to the pure colors of the spectrum. We are talking about orange, red, violet, green, yellow, and blue. The prices of very dark are very pale semiprecious and precious gemstones are lower in value.
The cut of the gemstone is one of the most important traits in determining gemstone value. The cut has to be done in a way that reflects light back to the viewer. A stone that has a poor cut can't reflect the light consistently over its surface. Tone, color saturation, and color hue will never be consistent.
Another factor to look at is the clarity of the gemstone under consideration. This refers to the gemstones purity with no internal conclusions, spots, or particles within the crystal structure. Without a doubt, zero flaws are hard to find and make your stones very valuable.
Next to consider are size and weight. Save for pearls and corals, all gemstones are priced by the carat. A carat is equal to 0.2 grams. Be aware however, that size and weight and gemstones are not the same. Density or specific gravity can very. Take a diamond that weighs 1.00 carats and you will see that a similar sized ruby or sapphire is 1.20 carats.
Taking up the hobby of gemstones can become an enjoyable pastime and also rewarding in the long run. You can start small and don't have to spend a lot of money and yet you can end up with some very beautiful stones. Many people love to set aside vacation or weekend time to go hunting gemstones.
