The Gemstones Review
Gemstone Information ArticleHow To Start Gemstone Collecting
By Lee MacRae
Gemology is a term referring to the profession, science, and even art of evaluating and identifying rocks known as
natural diamonds or
loose gemstones. Many people take up gemology more as a hobby. They become interested in collecting
loose gemstones or
loose diamonds. A number of these hobbyists start to visit various locations close by or possibly even in other countries to look for raw gemstones. Some of them will even tumble or finish off the gemstones themselves. If this hobby interest you read along as we reveal the various factors in gemstone collecting.
The very first step in beginning this hobby the proper way is through the power of knowledge. By taking a look in your local bookstore you can find books on the subject that will prevent you from making mistakes at the start.
Color is a very important part in giving value to a gemstone. The closer a color is to its purer spectral value the more valuable the stone becomes. Traditional spectral colors include violent, blue, green,, orange and red. Gemstones colors that are darker or palerthan a pure color tend to be less valued.
Gemstone cut is the next factor to look at before a purchase. The precision of the cut is the factor that determines the amount of light is reflected by the gemstone. It will fully ultimately determine the stones brilliance and how much someone will pay for it.
The next factor to look at is the clarity of the gemstone. This is talking about the purity of the gemstone or the absence of internal inclusions, particles or spots within the crystal. Without a doubt, zero flaws would make the gemstone highly valuable.
Gemstones are often listed according to their size aspect because it is more uniform than carat weight. But different gemstones may be the same size but have different carat weights that result in different pricing structures. This is due to the nature of gemstone difference of specific gravity or relative density and depends on the materials chemical composition and crystal structure type A one carat round brilliant diamond, for example with standard proportions will be approximately 6.5 mm in diameter. A comparable round brilliant ruby of the same size and proportions will weigh in at 1.55 carats instead.
Taking up the hobby of gemstones can give you an enjoyable pastime and rewarding in the long run. You can take your time and not lay out a lot a cash at the start and yet you can end up with some very beautiful stones. Many people love to set aside vacation or weekend time to go hunting for raw gemstones. Take the example of the US. In Virginia you can find Amethyst, Garnet, Beryl and Moonstone. And if you like to travel farther you can find opal in Opalton, Yowah, Queensland, Austalia, topaz in Beechworth, Victoria or hunt the quartz regions in Beechworth and Mooralla in Victoria Australia.

Topaz is a very large stone. One giant gem at the Viennese Historical museum is
reputed to weigh 585,000 carats. The rarest topaz is the Imperial Topaz and pink
topaz. Pakistan is the only place today where rose-red tinted topaz can be found
today. All other pink topazes get their color from heat treatments of up to 475?
C. Imperial topaz is has a yellow tint to it while other members of the topaz
family can be completely colorless. Some of the most beautiful examples of topaz
are the famous blue topaz which can have colorful ranges starting with light
blue stones. The very deep blue topaz is artificially produced by heating and
irridation processes. One of the most interesting characteristics about topaz is
that it bleaches in daylight and then renews itself as the light subsides. The
color changes occur because of natural heating and irridation.

Rubies and sapphires are different colored varieties of the mineral corundum.
Now corundum is a fairly common mineral. Second only to diamond in hardness it
has been mined extensively for abrasives. The emery on your emery boards and
sand paper is corundum. Gem quality corundum is quite a bit rarer, consisting of
only a percent or so of all the corundum found. The most common of the gem grade
corundum is blue sapphire. Sapphire comes in every color of the rainbow and the
other colors are rarer than the blues. This may be a bit of a surprise as the
blue ones are so valuable. However, the law of supply and demand comes in here.
Most of the people wanting a sapphire are looking for a deep blue gemstone, not
something yellow or green. Hot pink sapphires and the pinkish orange variety
know as padparasha do demand a high price in the market place. Generally though,
it is the demand for blue gems that fuels the pricing here.

Collecting Prescious And Semi-Prescious Gemstones
By Lee MacRae
Why collect
loose gemstones you ask? For many people it's because they are very beautiful items. And like their higher counterpart,
natural diamonds they can appreciate in value over time. Many in this hobby love to find, collect and finish each and every one of the 150 varieties available. Follow along as we look at the hobby of collecting
loose gemstones.
To start off right you need to read up on the various gemstones available. You'll find it very helpful to know what you're buying and prevent you from making mistakes. This will help you make informed decisions.
Color is a very important part in evaluating a gemstone. The closer the color of the gemstone is to its purer spectral value the more highly prized it is. Traditional spectral colors are orange, green, yellow, Violet and blue. Colors that are paler or darker than the pure color are considered a lower value.
The cut of the stone is extremely important and factors into appraisal of diamonds along with gemstones. A precision cut gemstone showcases the pure color of the stone, lessen any inclusions and show off its symmetry and proportions. One way to determine the precision in the cut is to look at how well and consistent it reflects light over its entire surface. If the stone is cut on the shallow side much of the light will refract out of the gem instead of reflecting internally. Gemstone color will be washed out.
The clarity in a stone is the next item to consider. Clarity refers to a stones relative freedom from inclusions or blemishes. The gemstone without flaws is more valuable. To examine flaws not seen with the naked eye you need a 10X gemstone loupe (gemstone clarity magnifier) or gem microscope. Most hobbyists will get an inexpensive 10X gemstone or jewelers loup for examining coins, stamps and of course gemstones.
Next comes size and weight. Except for corals and pearls, all gemstones are priced by the unit, carat. One carat equals a 0.2 grams. Be aware however, that weight and size are not the same in gemstones. Density or specific gravity can vary in gemstones. Take a diamond that weighs 1.00 carats and you will see that a similar sized sapphire or ruby weighs out at 1.20 carats.
Taking up the hobby of gemstones can be very enjoyable and could be rewarding as well over time. You can take your time and not lay out a lot a cash at the start and yet you can buy some very beautiful items. Many people love to set aside vacation or weekend time to go hunting gemstones. Take the example of the US. In Virginia you can find Amethyst, Garnet, Beryl and Moonstone. Or ou can take a longer vacation and find opal in Coober Pedy, Andamooka or Mintabie in South Australia, topaz in Torrington, New South Wales, Australia or hunt in the garnet fields in Fullarton River in Queensland, Australia.

Hints About natural yellow diamonds
Very Good Grade diamonds: This grade also has high brilliance and scintillation,
but expect them to be a bit darker in the center or around the edges. In some
cases a diamond can have top brilliance and scintillation, but be down graded by
its pattern. The stone above has a splintery pattern that prevents it from being
graded excellent.

The weight of a diamond is measured in carats (ct.). Each carat is divided into
100 points. For example: 1ct.= 100 points, 1/2 ct. = 50 points. Points in a
fraction are measured within acceptable ranges. For example: a 1/2 ct diamond
pendant may have a range of + or - .06 points. In other words, the total diamond
weight may vary from .44 to .56 points and still be considered a 1/2 carat.

Using gemstones is easy. Simply carrying the stone in your pocket or purse and
touching it from time to time during the day brings your awareness back to your
goal or intention. Placing it in your pillow case at night or on your desk where
you can see it is another way it incorporates in your life. A tumbled gemstone
is small enough to carry in your pocket or put into your pillow case without
weighing you down. They are pretty and affordable, too! Of course, wearing
gemstone jewelry like a necklace, bracelet or earrings is very effective and
attractive as well. Here are a few gemstones you may want to consider.

Our Featured Gemological ArticleThe Hobby Of Loose Gemstone Collecting
By Lee MacRae
Gemology is the science, art and profession of identifying and evaluating rocks known as
natural diamonds or
loose gemstones. A number of people taken up gemology more as a hobby. They become interested in collecting
loose diamonds or
loose gemstones. A number of these hobbyists start to travel to various locations nearby or even different countries to look for rough gemstones. Some of them will even tumble or finish off the gemstones themselves. If this hobby interest you follow along as we discuss the various factors in gemstone collecting.
First off you'll need the knowledge on each of the gemstones out there. This will help you to know what exactly you're looking for and prevent you from wasting your money. Without the proper knowledge you can make costly mistakes.
The first item to take into account will be the color of the gemstone. You'll want the gemstone to be as close as possible to the pure spectrum colors. This means blue, green, yellow, orange, red and violet. The prices for very pale or very dark semiprecious and precious gemstones are lower than the vibrant colors.
Gemstone cut is very important and factors highly into the appraisal of not only diamonds but gemstones in general as well. A precision cut will highlight the natural color of the gemstone, lessen any inclusions and show off its symmetry and proportions. One way of determining the excellence of the cut of the stone is to consider if it is able to reflect light on a consistent level throughout its surface. If the gemstone is cut to shallow most of this light were refracted away instead of reflecting inside the gemstone. That will make the gem seem washed out and windowed.
The next factor to consider is the clarity of the gemstone. This means the purity of the gemstone or the lack of internal inclusions, spots, or particles within the crystal structure. Obviously, stones with a lack of flaws will make a gemstone very valuable.
Gemstones are often categorized according to their size aspect because it is more uniform than carat weight. But different gemstones may be of the same size but differ in carat weights and as a result different prices as well. This is due to the difference in relative density or specific gravity and depends on the materials chemical composition and characteristic 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.
Collecting various gemstones can be a great hobby. And there are so many different types when it comes to gemstones. You can collect gemstones like Agate, Agate or Axinite for instance. The varieties are nearly endless. And if you like to save money but love vacations you can go gemstone hunting and find the raw materials instead of buying them. Take the example of the United States. In New Hampshire you can rock hunt for Beryl, Rock Crystal and Garnet.

Our Featured Gemstone ArticleThe Hobby Of Loose Gemstone Collecting
By Lee MacRae
The term gemology refers to the science, art and profession of identifying and evaluating gemstones from
loose gemstones to
natural diamonds. A number of people taken up this profession more as a hobby. They collect and evaluate items like
loose gemstone or
natural diamonds. A number of these hobbyists start to visit different local areas to look for raw gemstones. Some even tumble or learn to cut their own gemstones. If this hobby interest you read along as we show you the in and outs of gemstone collecting.
To start off right you'll need the knowledge on the wide variety of stones available. You'll find it very helpful to know what you're buying and prevent you from wasting your money. This will help you make informed decisions.
The chief thing you need to look at will be the color of the stone. You'll want the stone to be as close in color as possible to the pure spectral colors. The spectral colors are red, orange, yellow, green, blue, and violet. In general terms, the prices of very dark are very pale precious and semi 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 highlights the pure color of the stone, lessen any inclusions and highlight the proportions and symmetry of the stone. One way of determining the excellence in gemstone cut is to consider how consistently it reflects the light over the stones complete surface. But if a gem is cut too shallow, most of this light were refracted away rather than reflecting internally. Gemstone color will be washed out.
The clarity of a gemstone is the next item to consider. Gemstone clarity relates to the amount of inclusions (trace elements or large particles of other elements or minerals) that a gem has. The gemstone without flaws is more valuable. To see flaws beyond with the eye can see you need a gemstone loupe (gemstone clarity magnifier) or gem microscope. Many hobbyists will use a 10X jewelers were gemstone loup for viewing stamps, coins, beads as well as gems.
Next thing to look at is the duo of size and weight. Due to the fact gemstones can vary greatly in density and specific gravity. Weight and size are not necessarily equal across the board. If a diamond of a certain size weighs 1.00 carats then an equal sized Sapphire would weigh more than 1.20 carats. An equal sized Emerald would be 0.95 carats while an Alexandrite gem stone would came in at 1.23 carats.
Taking up the collecting of loose gemstones can create an enjoyable hobby and pastime. And there is such a variety when it comes to gemstones. You could try collecting Garnet, Pyrite or Kornerupine and then try others. The opportunities are seemingly endless. And if money is tight you can go gemstone hunting and find the raw materials instead of buying them. Take the example of the United States.
