The Hobby Of Loose Gemstone Collecting
By Lee MacRae
Many people, young and old, say collecting various loose gemstones or loose diamonds is a favorite pastime. They love the colors and the beauty of the wide array of gemstones you can find just about everywhere in the world. Read long as we look at a number of factors you should understand in starting in this hobby.
The first thing you need to do is to get some books from the library or bookstore. You want to understand as much as possible about the subject of gemstones. The more you learn about each kind of gemstone the less likely you are to make a mistake. You will know exactly what to look for.
First, color is a major part in giving value to a gemstone. The closer the color comes to its purer spectral value the more valuable the stone becomes. Traditional spectral colors include violent, blue, green,, orange and red. Colors that tend to be darker or palerthan a pure color diminish the value of the stone.
The cut of the stone is extremely important and factors into appraisal of diamonds but along with your gemstones. A precision cut gemstone showcases the pure color of the stone, diminishes its inclusions, and exhibits good overall symmetry and proportion. One way of determining the excellence regarding the cut is how consistently it reflects the light throughout its surface. If the gemstone is cut to shallow most of this light were refracted away rather than reflecting internally. Gem color appears washed out.
A third consideration is the stone's clarity. This refers to the stones purity or the lack of internal inclusions, 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 weight and size. Other than the corals and pearls gemstones are priced by the carat. One carat is the equivalent of 0.2 grams You should know however that weight and size are not always equal and gemstones. The density and specific gravity can differ in stones. Take a diamond that weighs 1.00 carats and you will see that a similar sized ruby or sapphire is 1.20 carats.
Collecting gemstones can create an enjoyable hobby and pastime. And there is a wide range and variety in gemstones you can collect. You can start collecting gemstones like Hematite, Amethyst (cardinal gem) or Tourmaline for instance. The opportunities are seemingly endless. And if you like a hands on hobby you can find gemstones for yourself instead of buying. Take the example of the United States. In North Carolina you can find Beryl, Aquamarine, Emerald, Almandite Garnet, Rhodolite, and Pyrope Garnet, Diamond, Cyanitecomma
