Gemological Article Of The MonthSo You Want To Collect Loose Gemstones
By Lee MacRae
Many people today say collecting various
loose gemstones or
loose diamonds is a favorite pastime. They love the colors and the beauty of the various gemstones found around the world today. This article will examine the things you need to know when starting to collect gemstones yourself.
The very first step in becoming a gemstone collector the intelligent way is by acquiring knowledge about them. By taking a quick trip to the library or local bookstore you can find books on the subject that will let you make wise purchases from the beginning.
One of the first things you look at Is gemstone color. Highly prized gemstones exhibit colors similar in pureness to the spectral colors of orange, green, yellow, Violet or blue. Gemstone colors that are muted or on the dark side can lower the value.
How a stone is cut is the second most important factor to consider. The precision of the cut determines the amount of light the gemstone stone will reflect. The cut will determine the brilliance of the stone and how much it will be valued.
The next factor to look at is the gemstone's clarity. This refers to the stones purity or the lack of internal inclusions, particles or spots within the crystal structure. Needless to say, stones with no flaws will make a gemstone very valuable.
Next on the agenda is the duo of weight and size. Due to the fact gemstones can vary greatly in density and specific gravity. Weight and size are not equal for each and every stone. If a diamond of a certain size weighs 1.00 carats then an equal sized Sapphire would weigh more than 1.20 carats. An emerald stone would be about 0.95 carats and an Alexandrite stone would be about 1.23 carats.
Taking up the hobby of gemstones can give you an enjoyable pastime and also 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 take vacations to go hunting for raw gemstones. Take the example of the US. In Florida you can find Chalcedony and Conch Pearl. Or you can take the time to travel and find opal in Coober Pedy, Andamooka or Mintabie in South Australia, topaz in Beechworth, Victoria or hunt in the garnet fields in Fullarton River in Queensland, Australia.

In Australia, Cambodia and Thailand sapphires have developed over millions of
years from rich deposits of molten carbonatite that has a lot of aluminum mixed
with it. At first they were situated deep in the earth's crust where there was a
presence of high pressure and extremely high temperatures. It was basalt
volcanic activity that propelled them to the surface along with other minerals,
and finally they were laid to rest on the valley floors.

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.

Gemstone Article Of The MonthSo You Want To Collect Gemstones
By Lee MacRae
Many people, young and old, say collecting various
loose gemstones or
loose diamonds is a favorite pastime. Many people have a great love of the various gemstones found worldwide today. This article will look at a number of factors you should understand when starting to collect varieties of gemstones yourself.
At the very beginning you need to read up 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 making mistakes. Get the answer to questions like how, where and what to buy.
Color is a very important part in evaluating a gemstone. The closer the color of the gemstone is to its pure spectral color the more valuable the stone becomes. Traditionally, these specter 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.
Cut is one of the all-important 4Cs and factors highly into the appraisal of not only diamonds but gemstones in general as well. A precision cut gemstone highlights the natural color of the gemstone, lessen any inclusions and highlight the proportions and symmetry of the stone. One excellent way to determine the excellence of the cut is to look at 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 inside the gemstone. That will make the gem seem washed out and windowed.
Another factor to look at is the clarity of the gemstone. This means the gemstones purity or the absence of internal inclusions, spots, or particles inside the crystal. Obviously, stones with a lack of flaws will make a gemstone very valuable.
Gemstones are often categorized according to their size aspect since it is more uniform than carat weight. But two different gemstones may have the same size but have different carat weights that result in different in prices as well. This is due to the difference in relative density or specific gravity depending upon the materials chemical composition and crystalline structure. For example, a one carat round diamond of typical proportions will be approximately 6.5 mm in diameter. A ruby that is the same size will weigh in at 1.55 carats.
Collecting gemstones can be a great hobby. And there is such a variety in precious and semi precious stones that you can collect. You could try collecting Lapis lazuli, Pyrite or Kornerupine for instance. The choice and beauty and variety is almost endless. And if money is tight you can go hunting for raw gemstones. For example in Alaska you can find White Quartz and Jade.

mind and prevented sudden death. Some physicians of those times prescribed it as
a remedy for weak vision. It was also used as a method of preventing mental
disorders or curing these disorders altogether.

Think twice before putting gems in an ultrasonic cleaner. Diamonds, rubies and
sapphires will be fine but many other gems may not be: when in doubt, leave it
out. Diamonds, rubies and sapphires, and other single-crystal gems can be
cleaned with a touch of ammonia in water to remove all films and add extra
sparkle. Never use an ultrasonic cleaner or ammonia for cleaning such opaque
gemstones like lapis, turquoise, malachite or onyx. They should be wiped clean
gently with a moist cloth. These gemstones can be porous and may absorb
chemicals, even soap, which may build up inside the stone and discolor it. The
reason why these materials need more care than transparent gemstones is that
these materials are essentially rocks, not crystals of a single mineral. Think
about it: when you put a rock in water, it absorbs the water and is moist all
the way through. A single crystal gem like sapphire will not absorb water: all
the molecules are lined up so tightly in the crystal that there is no room for
water to enter.

So You Want To Collect Gemstones
By Lee MacRae
Gemology is a term referring to the art, profession and science of evaluating and identifying gemstones from
loose gemstones to
natural diamonds. A number of people taken up this profession more as a hobby. They become interested in collecting items like
loose gemstone or
natural diamonds. A number of these hobbyists start to visit different areas nearby or in other countries to look for raw gemstones. Some even tumble or learn to cut their own gemstones. If this hobby interest you read along as this article discusses the different aspects of this hobby.
To begin with 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 first criteria you need to evaluate is stone color. It is a fact that gemstones are the most intensely colored naturally occurring materials you can find. These materials are so related to their color that they've even had their names combined with associated colors. You've no doubt heard about emerald green, ruby red, sapphire blue, jade green, turquoise or aquamarine. Gemstones are valued much higher they closer they are to natural spectral colors of red, orange, yellow, green, blue, and violet. They are valued much less when they are lighter or darker than the natural color.
The cut of your gemstone is one of the most important traits in determining gemstone value. The stone has to be cut in a way that reflects light back to the viewer. A stone that has a poor cut will never be able to reflect light consistently. Color tone, saturation, and hue will never look consistent.
The next factor to look at is the clarity of the gemstone. This refers to the purity of the gemstone with no internal conclusions, internal particles or spots within the crystal. Without a doubt, zero flaws would make the gemstone highly valuable.
Next to consider are size and weight. Except for corals and pearls, all gemstones are priced by the unit, carat. One carat equals a 0.2 grams. However you should know weight and size are not the same in gemstones. Density or specific gravity can vary in gemstones. Take a diamond that is 1.00 carats in weight and you will find that a similar sized ruby or sapphire is 1.20 carats.
Taking up the collecting of loose gemstones can be very rewarding hobby. And there is a wide range and variety in gemstones you can collect. You can collect gemstones like Jade [jadeite and nephrite], Sugilite Natural moissanite and then try others. The choice and beauty and variety is almost endless. And if money is tight you can find gemstones for yourself instead of buying. For example in Oregon you'll find Agate, Obsidian, Hydrolite and Sunstone.

Selenite helps to align you with higher consciousness. As you develop
spiritually it is beneficial to allow yourself to listen to or sense guidance
from your higher self, spirit guides or angels. This stone opens the crown
chakra to receive transmissions of information and wisdom. On a physical level
it helps with the spine, bone and muscular structure of the body. Selenite is a
white stone, though recently I have found red selenite (it looks orange to me)
that can re-align the emotional structure of one�s consciousness.
