The Hobby Of Gemstone Collecting


By Lee MacRae


Why collect loose gemstones you ask? Well for one thing gemstones are extremely beautiful. And just like natural diamonds their value increases over time. Many in this hobby love to collect and work with the wide variety of gemstones available today. Follow along as we look at the hobby of collecting loose gemstones.


Right at the beginning, what you need is to get some books from the library or bookstore. You want to learn everything there is to know about your new hobby. The more you know about each kind of gemstone the better off you'll be. You'll know exactly what to buy.


The first item to factor in is gemstone color. You'll want the stone to be as close as possible to the pure spectrum colors. We are talking about red, orange, yellow, green, blue, and violet. The prices of very dark are very pale semiprecious and precious gemstones are lower in value.



Gemstone cut is very important and factors into appraisal of diamonds but gemstones in general as well. An excellent cut will highlight the pure color of the stone, diminishes its inclusions, and exhibits good overall symmetry and proportion. One excellent way to determine the excellence in the cut is to look at if it is able to reflect light on a consistent level throughout its surface. If the gemstone is cut to shallow most of the light will refract out rather than reflecting inside the stone. That will make the gem seem washed out and windowed.


The clarity in a stone is the next item to consider. Gemstone clarity relates to a stones relative freedom from inclusions or blemishes. Generally speaking, a clearer stone is definitely worth much more. To determine the flaws not seen with the unaided eye you need a gem microscope or 10X gemstone clarity magnifier. Most hobbyists will get a jewelers diamond gemstone loupe 10X for viewing stamps, coins, beads as well as gems.


You will note that gemstones are categorized according to their size aspect since it is more uniform than carat weight. But two different gemstones may be the same size but have different carat weights that result in different in prices as well. This factor comes from the difference in relative density or specific gravity 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 a brilliant ruby of the same proportions in size will weigh in at 1.55 carats.


Taking up the collecting of loose 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 Aquamarine and other varieties of beryl, Topaz or Natural moissanite for instance. The varieties are nearly endless. And if you like to save money but love vacations you can go hunting for raw gemstones. For example in Maine you can find Tourmaline, Beryl, Rose Quartz, Pearl, Topaz, Amazonite, Clear & Smoky Quartz and Aquamarine.

Many natural gemstones such as the ruby, sapphire, and emerald are becoming so rare and expensive to mine that laboratory-grown gemstones are used often in jewelry designs. The first lab-grown gemstone was produced in 1902 in Paris, France by a chemist named Louis Verneuil. A gemstone that is grown in a laboratory is not imitation or artificial, and is carefully crystallized over time. It has essentially the same optical, physical and chemical properties as a natural gemstone. Only a trained gemologist can tell them apart. Natural gemstones such as rubies and emeralds can be 10 to 50 times more expensive than the cost of a lab-grown gemstone in a similar quality. And laboratory-grown emeralds and rubies are often superior to natural stones in both clarity and color.
