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.

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.
