Collecting Loose Gemstones

By Lee MacRae

Why would anyone collect items like loose gemstones, you ask? Well for one thing they've been sought for their beauty for many centuries. And like their higher counterpart, natural diamonds they can become extremely valuable over the years. Many in this hobby love to collect and work with the wide variety of gemstones available today. Follow along as we examine the loose gemstones hobby.

To begin with your first priority is to get some books from the library or bookstore. You want to know everything there is to know about your new hobby. The more you learn about the hobby of gemstones the wiser will be your purchases. With adequate knowledge you are less likely to be fooled.

First on your list to factor in is stone color. You want the stone to be as close in color as possible to the pure spectrum colors. The spectral colors are red, orange, yellow, green, blue, and violet. The prices of very dark are very pale stones are less per carat.

How a gemstone is cut is the second most important factor to take a look at. The precision of the cut is the factor that determines the amount of light is reflected by the gemstone. It will fully factor highly in the brilliance of the stone and how much it will be valued.

Another factor to look at is the clarity of the gemstone under consideration. This means the stones purity with no internal conclusions, internal particles or spots within the crystal structure. Without a doubt, zero flaws are hard to find and make your stones very valuable.

Next on the agenda is the duo of size and weight. Due to the fact gemstones can vary greatly in density and specific gravity. Size and weight are not necessarily equal from stone to stone. If a diamond of a certain size weighs 1.00 carats then a sapphire of equal size would weigh 1.20 carats. An Emerald of equal size would be approximately 0.95 carats while an Alexandrite stone would be about 1.23 carats.

Getting involved in collecting gemstones can become an enjoyable pastime and rewarding in the long run. It doesn't have to be very expensive and yet you can buy some very beautiful items. Many people love to take vacations to go hunting gemstones. Take the example of the United States. In Maine you can find Tourmaline, Beryl, Rose Quartz, Pearl, Topaz, Amazonite, Clear & Smoky Quartz and Aquamarine. And if you like to travel farther you can find opal in Opalton, Yowah, Queensland, Austalia, topaz in Torrington, New South Wales, Australia or hunt specimens the quartz regions in Wave Hill in the Northern Territory of Australia.

Starting The Hobby Of Gemstone Collecting

By Lee MacRae

Gemology is the art, profession and science of evaluating and identifying gemstones from natural diamonds to loose gemstones. A number of people taken up gemology as a passionate hobby. They become interested in collecting and evaluating items like loose gemstone or natural diamonds. Some people even begin to visit different areas nearby or in some cases other countries to look for rough gemstones. Some hobbyists will learn to cut or tumble the gemstones they find. If you have an interest in this hobby then follow along as we discuss the various aspects of gemstone collecting.

First off you need to learn all you can on the wide variety of stones available. You'll find it very helpful to know what exactly you're looking for and prevent you from wasting your money. Without the proper knowledge you can make costly mistakes.

Of paramount importance Is gemstone color. Highly prized gemstones exhibit colors similar to the exact spectral color of orange, green, yellow, Violet or blue. Gemstone colors that are muted or on the dark side can lower the value.

Stone cut is the next factor to consider. How precise the cut is is the factor which determines how much light is reflected by the gemstone. The cut will ultimately determine the stones brilliance and how much someone will pay for it.

Another factor to look at is the clarity of the gemstone. This means the purity of the stone or the lack of internal inclusions, particles or spots inside the crystal. Needless to say, stones with no flaws would make the gemstone highly valuable.

The next factors to consider our size and weight. Save for pearls and corals, all gemstones are priced by the carat. One carat equals a 0.2 grams. You should know however that weight and size are not always equal and gemstones. Density or specific gravity can very. Take a diamond that is 1.00 carats in weight and you will find that a similar sized sapphire or ruby weighs out at 1.20 carats.

Though you may find gemstones used a lot in jewelry, loose gemstones are great for collecting. Actually there are many interesting and attractive gems that are just too big or fragile to be used for jewelry. Look at each loose gemstone and Think of it as a mini sculpture or piece of art to be highly treasured for its unique nature and vibrant colors. And in this hobby you don't have to always lay out cash because you can actually go hunting for raw gemstones in the field. In the United States in New Jersey you can find Smoky Quartz, Agate, Pearl and Prehnite. And if you travel to Canada you will find rhodonite at various locations in British Columbia or amazonite (microcline) near Lac St-Jean, Quebec as well as zircons in Sebastopol and Brudnell Townships in Renfew County, Ontario. Take up gemstone collecting and you won't regret it.

In parts of the world sapphires may have come from ancient formations that were
once impure marble which developed over time through metamorphic conditions into
crystalline cal silicates known as skarns. A skarn is a metamorphic rock that is
usually variably colored green or red, occasionally grey, black, brown or white.
It usually forms by chemical processes that form rocks during metamorphism and
in the contact zone of magma like intrusions. Skarns in the igneous environment
are associated with marble and wider zones of cal silicate rocks. Mixtures of
corundum, titanium and iron were also a part of the crystallization process.
Because of this process there are numerous inclusions in a sapphire, and like
the ruby, they are useful in verification techniques when authenticating the
stone.
