The Best Information On Gemstones
Gemological Article Of The MonthStarting To Collect Gemstones
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 this profession as a hobby. They become interested in making a collection of loose gemstones or loose diamonds. You'll even find some that like to visit various local locations to look for rough gemstones. Some of them will even tumble or finish off the gemstones themselves. If this hobby interest you follow along as we discuss the different aspects of this hobby.
At the very beginning you need to read up on the wide variety of stones available. You'll find it very helpful to know what you're buying and prevent you from wasting your money. Without the proper knowledge you can make costly mistakes.
First, color is a major part in the value of the stone. The closer a color is to its purer spectral value the more highly prized it is. Traditionally, these specter colors are orange, green, yellow, Violet and blue. Colors that tend to be darker or paler diminish the value of the stone.
Gemstone cut is easily one of the most important aspects in determining gemstone value. The stone has to be cut correctly to reflect light properly. A gemstone with an improper cut can't reflect the light consistently over its surface. Color saturation, hue and tone will be inconsistent.
Gemstone clarity is an important consideration. When we talk of clarity it relates to the absence of flaws or blemishes inside the stone. A flawless gemstone is obviously worth more. To examine flaws not seen with the naked eye you need a gem microscope or 10X gemstone clarity magnifier. Serious hobbyists will buy an inexpensive 10X gemstone or jewelers loup for viewing stamps, coins, beads as well as gems.
Next item to look at is the duo of weight and size. Because gemstones can vary in density or specific gravity. Weight and size are not equal for each and every stone. Take the example of a diamond that weighs 1.00 carats and a sapphire of equal size would weigh 1.20 carats. An emerald stone would be about 0.95 carats and an Alexandrite stone would be about 1.23 carats.
Collecting various gemstones can create an enjoyable hobby and pastime. And there is a wide range and variety when it comes to gemstones. You could try collecting Jade [jadeite and nephrite], Pyrite or Tourmaline for example. The opportunities are seemingly endless. And if you like a hands on hobby you can go hunting for raw gemstones. Just in the United States in Minnesota you can hunt for Agate and Thomsonite.
