Starting To Collect Gemstones
By Lee MacRae
Why collect loose gemstones you ask? Well for one thing they are very beautiful items. And just like natural diamonds they can become extremely valuable over the years. Many hobbyists love to find, collect and finish the nearly 150 types of gemstones found today. Follow along as we discuss the hobby of loose gemstone collecting.
Right at the beginning, what you need is to get yourself some reading material. You want to understand as much as possible about the subject of gemstones. The more you know about the hobby of gemstones the less likely you are to make a mistake. You'll know exactly what to buy.
The first item to factor in is gemstone color. You want the gemstone to be as close as possible to the pure colors of the spectrum. This means blue, green, yellow, orange, red and violet. The prices for very pale or very dark semiprecious and precious gemstones are lower.
The cut of the stone is extremely important and factors into appraisal of diamonds but you're gemstones as well. A good cut showcases the natural color of the gemstone, lessen any inclusions and highlight the proportions and symmetry of the stone. One way to determine the precision regarding the cut of the gemstone is if it is able to reflect light on a consistent level over the stones complete surface. If the gemstone is cut to shallow most of the light will refract out instead of reflecting internally. That will make the gem seem washed out and windowed.
Gemstone clarity is an important consideration. Gemstone clarity relates to a stones relative freedom from inclusions or blemishes. A gemstones that is normally found to be clean is obviously worth more. To see flaws beyond with the eye can see requires a 10X gemstone clarity magnifier or gem microscope. Serious hobbyists will use an inexpensive 10X gemstone or jewelers loup for examining coins, stamps and of course gemstones.
Next comes weight and size. Save for pearls and corals, all gemstones are valued by the unit called the carat. One carat equals a 0.2 grams. Be aware however, that size and weight and gemstones are not the same. Density or specific gravity can very. 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.
Collecting gemstones can be a great hobby. And there is such a variety when it comes to gemstones. You can start collecting gemstones like Garnet, Sugilite Cassiterite for example. The choice and beauty and variety is almost endless. And if you like to save money but love vacations you can find gemstones for yourself instead of buying. Take the example of the United States. In Arizona you can find Agatized wood (Petrified wood), Azur-Malachite, Turquoise, Garnet, Peridot, Jasper and Moissanite
