By Lee MacRae
Many people, young and old, say collecting semi-precious and precious gemstones like loose diamonds or loose gemstones is a passionate hobby. Many people have a great love Of the assorted number of gemstones found worldwide today. Follow along as we discuss a number of things you need to know when starting this gemstone hobby.
First off you'll need the knowledge on the wide variety of stones available. This knowledge will help you to know what exactly you're looking for so you buy the right items. A knowledgeable buyer is a wise one.
To start with, an important aspect in gemstone evaluation is color. Gemstones are the most intensely colored natural materials you can find. Gems have become so synonomous with color, they have even lent their names to specific colors. Everyone knows ruby red, emerald green, sapphire blue, aquamarine, turquoise, and jade green Gemstones become higher in value the closer they are to the colors in the spectrum of violet, blue, green,, orange and red. They are valued much less the farther they deviate from the pure natural color.
The cut of the stone is extremely important and factors highly into the appraisal of not only diamonds but gemstones as well. A precision cut will highlight the pure color of the stone, lessen any inclusions and highlight the proportions and symmetry of the stone. One excellent way to determine the excellence of the cut of the stone is to consider if it is able to reflect light on a consistent level over the stones complete surface. If the gemstone is cut to shallow much of the light will refract out of the gem instead of reflecting inside the gemstone. The gem appears washed out.
Next up is the aspect of gemstone clarity. Clarity refers to the internal flaws (inclusions) or the external blemishes of a stone. Larger flaws can easily be seen with the unaided eye while others require close examination using a 10X magnification.
Next to consider are size and weight. Except for corals and pearls, all gemstones are valued by the unit called the carat. A carat is equal to 0.2 grams. You should know however that weight and size are not the same in gemstones. Density or specific gravity can very. If you have a diamond that weighs 1.00 carats, you will find a similar sized sapphire or ruby weighs out at 1.20 carats.
Collecting various gemstones can create an enjoyable hobby and pastime. And there is a wide range and variety in precious and semi precious stones that you can collect. You can collect gemstones like Chrysocolla, Sugilite Zeolite (Thomsonite) and then try others. The varieties are nearly endless. And if money is tight you can go gemstone hunting and find the raw materials instead of buying them. For example in Michigan you can find Agate, Chlorastrolite and Hematite.

Within each gemstone variety, quality dramatically affects price: a gem can sell
for $100 or $2,000,000. When buying a gemstone - buy the best quality, most
experts recommend. Choose a smaller stone of higher quality over a larger stone
of lower quality, or buy a higher quality gem from an unusual variety if your
budget is too small.

There are many other common types of treatment to enhance the beauty of colored gemstones. Emeralds are often oiled and waxed to protect them and to hide fine lines that naturally occur in the stone. Some sapphires have their blue color enhanced using diffusion, a chemical process. Certain stones are treated with radiation, again mimicking the processes of nature. All these practices are standard in the jewelry industry; in fact, enhancement is so common that good quality unenhanced stones often come with a certificate stating that fact.

Collecting Prescious And Semi-Prescious Stones
By Lee MacRae
For many people collecting loose gemstones or loose diamonds is their favorite hobby. They love the colors and the beauty of the various gemstones you can find just about everywhere in the world. Follow along as we discuss a number of things you need to know in starting in this interesting hobby.
To start off right you need to learn all you can on the various gemstones available. This knowledge will help you to know what exactly you're looking for and prevent you from making mistakes. A knowledgeable buyer is a wise one.
To start with, an important aspect in gemstone evaluation is color. Without a doubt, gemstones are the most intensely colored naturally occurring materials you can find. Gemstones are so related to color that they've even become associated with particular ones. Without a doubt you will recognize sapphire blue, ruby red, jade green, aquamarine, emerald green or turquoise. Gemstones will have a higher value the closer they are to the colors in the spectrum of orange, green, yellow, violet and blue. They become less valuable the more they deviate from the spectral color.
The cut of the stone is extremely important and factors highly into the appraisal of not only diamonds along with gemstones. An excellent cut will highlight the natural color of the gemstone, diminishes its inclusions, and show off its symmetry and proportions. One excellent way to determine the excellence of gemstone cut is to consider how well it reflects light on a consistent basis throughout the surface of the stone. If the gemstone is cut to shallow most of this light were refracted away instead of reflecting internally. Gem color appears washed out.
Next to look at is the aspect of gemstone clarity. Clarity is the term that refers to the internal conclusions or flaws of a stone being considered. Any large flaws can easily be seen with the unaided eye while others require close examination using a 10X magnification.
Next thing to look at is the duo of weight and size. Because gemstones can vary in density or specific gravity. Size and weight are not necessarily equal from stone to stone. Take the example of a diamond that weighs 1.00 carats and an equal sized Sapphire would weigh more than 1.20 carats. An Emerald of equal size would be approximately 0.95 carats while an Alexandrite gemstone would be about 1.23 carats.
Taking up the collecting of loose gemstones can be a great hobby. And there is a wide range and variety in precious and semi precious stones that you can collect. You could try collecting Olivine (Peridot), Sapphire or Benitoite and then try others. The opportunities are seemingly endless. And if money is tight you can go hunting for raw gemstones. For example in Alabama you can find Beryl, blue and yellow; Smoky Quartz and Hematite.

Color is a subjective idea but a very important part in evaluating a gemstone. The closer the color comes to its purer spectral value the more highly prized it is. Traditional spectral colors include violent, blue, green,, orange and red. Colors that tend to be paler or darker than the pure spectral color diminish the value of the stone.
The cut of the gemstone is an important factor to consider when you consider a gemstone's value. The gemstone must be cut with precision to reflect the light properly. A poor cut will not reflect light in a consistent way. Tone, color saturation, and color hue will never be consistent.
The next factor to consider is the gemstone's clarity. This refers to the stones purity or the lack of internal inclusions, internal particles or spots within the crystal. Without a doubt, zero flaws will make a gemstone very valuable.
Gemstones are often categorized according to size because of being more uniform than carat weight. But two different gemstones may be the same size but different carat weights and consequently, different prices as well. This is due to gemstone difference of relative density or specific gravity depending upon the chemical composition and crystalline structure. For example, a one carat round diamond with normal proportions is approximately 6.5 mm around. A ruby that is the same size will weigh approximately 1.55 carats.

Hints On loose diamonds
The sapphire has traditionally been involved in the area of religious magic, and
it was believed that the owner of the stone could use it to harness psychic
powers. It was, and still is, the choice of high church officials and regents
especially when their rings are mounted. There are several language origins for
the word "sapphire." In Sanskrit it was known as "sauriratna" in honor of the
planet Saturn. Ancient Chaldean references called it "sampir," while the Greeks
had a modern translation, "sappheiros" which denoted the color blue. The Arabic
translation was "safir" and the Latin texts call it "saphirus."
