Collecting Prescious And Semi-Prescious Stones


By Lee MacRae


Why would anyone collect items like loose gemstones, you ask? Well for one thing they are very beautiful items. And like their higher counterpart, natural diamonds their value increases over time. Many hobbyists love to collect and show case the wide variety of gemstones available today. Read long as we discuss the hobby of loose gemstone collecting.


Right at the start you need to read up on the wide variety of stones available. This will help you to know the properties of each stone so you buy the right items. Without the proper knowledge you can make costly mistakes.


To start with, an important aspect in gemstone evaluation is color. It is a fact that gemstones are the most intensely colored naturally occurring materials you can find. Gems have become so synonomous with color, they've even had their names combined with associated colors. You've no doubt heard about emerald green, ruby red, sapphire blue, jade green, turquoise or aquamarine. Gemstones become higher in value the closer they come to the natural spectral colors of yellow, blue, violet, green, orange and red. They are valued much less the farther they deviate from the pure natural color.


The cut of your gemstone is an important factor to consider when evaluating gemstones. The cut has to be done with precision to reflect the light properly. A poor cut will not reflect light consistently over its entire surface. Tone, color saturation, and color hue will never look consistent.


A third consideration is the clarity of the stone under consideration. This is talking about the purity of the gemstone or the lack of internal inclusions, spots, or particles inside the crystal. Needless to say, stones with no flaws will make a gemstone very valuable.


Another consideration is the duo of size and weight. Due to their nature gemstones can vary greatly in density and specific gravity. Weight and size are not equal for each and every stone. If you have a diamond that weighs 1.00 carats a ruby of equal size would weigh 1.20 carats. An equal sized Emerald would be 0.95 carats while an Alexandrite would be about 1.23 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 gems that are too fragile or too large to be used in jewelry. Here's a suggestion -- don't think of a gem as a component of jewelry; consider it as a piece of art and value it for its beautiful colors and the finish you apply to it. And unlike many hobbies where you have to buy everthing you can find your raw materials through field trips In the US in Montana you'll find Agate, Sapphire, Beryl, Amethyst, Smoky Quartz, Obsidian, Tourmaline and Garnet. And if you travel to Canada you will find nephrite jade in Mount Ogden, British Columbia or amazonite (microcline) near Lac St-Jean, Quebec as well as hessonite garnet in Asbestos, Quebec. Think of collecting gemstones as a great hobby and pastime.
