The Best Information On Gemstones
Starting The Hobby Of Gemstone Collecting
By Lee MacRae
Why collect
loose gemstones you ask? Well for one thing they are very beautiful items. And like their more familiar cousin,
natural diamonds, their value increases over time. Many in this hobby love to find, collect and finish the nearly 150 types of gemstones found today. Follow along as we discuss the hobby of
loose gemstone collecting.
To start off right you'll need the knowledge on the wide variety of stones available. This will help you to know what exactly you're looking for and prevent you from wasting your money. A knowledgeable buyer is a wise one.
Color is a very important part in giving value to a gemstone. The closer the color comes to its pure spectral color the more valuable the stone becomes. Remember that the spectral colors are orange, green, yellow, Violet and blue. Gemstones colors that are darker or palerthan a pure color diminish the value of the stone.
The cut of the gemstone is easily one of the most important aspects when you value gemstone. The cut has to be done in a way that reflects light back to the viewer. A gemstone with the poor cut can't reflect the light consistently over its surface. The color hue, color tone and saturation will always appear inconsistent
A third consideration is the clarity of the stone. This is talking about the purity of the gemstone with no internal conclusions, internal particles or spots within the crystal structure. Obviously, stones with a lack of flaws would make the gemstone highly valuable.
You will note that gemstones are categorized according to size since it is more uniform than carat weight. But two different gemstones may have the same size but differ in carat weights and as a result different prices as well. This factor comes from the difference regarding specific gravity depending upon 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 ruby that is the same size will weigh in at 1.55 carats instead.
Although gems are frequently used in jewelry, they are perfectly good collectibles in their own right. In fact, there are many attractive and interesting gems that are too fragile or too large to be used in jewelry. Take each loose gemstone and think of it as a piece of art, a miniature sculpture to be treasured for its beautiful colors and the finish you apply to it. And unlike many hobbies where you have to buy everthing you can find your raw materials through field trips In the US in Idaho you'll find Garnet, Opal, Agate, Obsidian and Sapphire. And in Canada you can find nephrite jade in the Frances Lake area in the Yukon Territory or sodalite and rose quartz near Bancroft, Ontario as well as amethyst from Nova Scotia. Think of gemstone collecting for the great hobby it is.

The common opal is quite a departure from the precious opal. There are several
different types of common opals: the milk opal, opals with blue and green tints,
resin opal, and a wood opal. There are also opals that can be found around hot
springs and geysers. They are a clear glass opal made up of geyserite. There are
other varieties of opals most notably the fire opal and Peruvian opal. Mexico
and Mesoamerica is the chief source of the fire opal. They come from the Mexican
high country where they can be found in rock surrounding extinct volcanoes. It
is extracted from open-pit mines in the canyons and valleys there. It should be
noted that more durable fire opals are found in drier region. The drier the
region the more durable the opal will be. While Mexico produces the most fire
opals they can be found in Honduras, Ethiopia, United States, Australia, Canada,
Turkey and areas in former Russian states.

Gemological Information ArticleCollecting Prescious And Semi-Prescious Stones
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 appreciate in value over time. Many people love to collect and work with each and every one of the 150 varieties available. Read long as we discuss the hobby of
loose gemstone collecting.
The very first step in starting the hobby of collecting gemstones the right way is through the power of knowledge. By taking a quick trip to the library or local bookstore you'll find numerous books on gemstones that will let you make wise purchases from the beginning.
The chief thing you need to factor in should be the color of the stone. You want the stone to be as close in color as possible to the pure spectral colors. We are talking about red, orange, yellow, green, blue, and violet. The prices for very pale or very dark semiprecious and precious stones are less per carat.
Gemstone cut is very important and is used not only to appraise diamonds along with gemstones. A good cut highlights the natural color of the gemstone, diminishes its inclusions, and exhibits good overall symmetry and proportion. 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 throughout its surface. If the gemstone is cut to shallow most of the light will refract out instead of reflecting inside. Gem color appears washed out.
A third consideration is the clarity of the stone under consideration. This means the gemstones purity or the absence of internal inclusions, particles or spots inside the crystal. Needless to say, stones with no flaws are hard to find and make your stones very valuable.
Next on the agenda is the duo of weight and size. Because 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 a ruby of equal size would weigh 1.20 carats. An emerald stone would be about 0.95 carats and an Alexandrite stone would be about 1.23 carats.
Collecting gemstones as a hobby 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 end up with some very beautiful stones. Many people love to take vacations to go looking for gemstones. Just in the United States in Utah You can find Topaz, Garnet, Petrified Wood, Jasper and Obsidian. And if you like to travel farther you can find opal in Opalton, Yowah, Queensland, Austalia, topaz in Killiecrankie, Tasmania or hunt in the garnet fields in Fullarton River in Queensland, Australia.

Dispersion is the splitting of white light into its spectral colours, as with light transmitted through a prism. It is also called fire when describing the dispersion seen in gemstones; diamond is a good example with a high dispersion value. Diamonds may be cut to increase dispersion at the sacrifice of brilliance or vice versa as described above in the brilliance description. The fire in opal is caused by the dispersion of light through its unique hydrous silica structure. The amount of dispersion in gemstones can be given in figures, but is generally described simply as low, medium and high.

Gemological Information ArticleThe Hobby Of Gemstone Collecting
By Lee MacRae
Gemology is the profession, science, and even art of evaluating and identifying rocks known as
natural diamonds or
loose gemstones. Many people take up gemology as a passionate hobby. They become interested in making a collection of
loose diamonds or
loose gemstones. A number of these hobbyists start to visit various locations close by to hunt for raw or rough gemstones. Some even tumble or learn to cut their own gemstones. If you have an interest in this hobby follow along as we show you the in and outs of gemstone collecting.
Right at the start 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. Without the proper knowledge you can make costly mistakes.
Number one to look at Is gemstone color. Highly prized gemstones have colors that are close to the purest spectral colors of orange, green, yellow, Violet or blue. Gemstone colors that are muted or on the dark side can lower the value quite easily.
The cut of your gemstone is one of the most important traits in evaluating gemstones. The gemstone must be cut correctly to reflect light properly. A stone that has a poor cut will not reflect light in a consistent way. The hue, tone and color saturation will never be consistent.
The clarity in a stone is our next factor. Clarity refers to the absence of flaws or blemishes inside the stone. A gemstones that is normally found to be clean is obviously valued highly. To see flaws beyond with the eye can see you need a gem microscope or gemstone clarity magnifier. Most hobbyists will buy an inexpensive 10X gemstone or jewelers loup for viewing stamps, coins, beads as well as gems.
The next factors to consider our size and weight. All gemstones [except for pearls and corals] are valued by the unit called the carat. A carat is equal to 0.2 grams. However you should know size and weight and gemstones are not the same. The density and specific gravity can differ in stones. Take a diamond that weighs 1.00 carats and you will see that a similar sized ruby or sapphire weighs 1.20 carats.
Taking up the hobby of gemstones can give you an enjoyable pastime and could be rewarding as well over time. You don't need to spend a lot of money and yet you can buy some very beautiful items. Many people loved to spend weekends to go hunting for raw gemstones. For example in Wyoming you can find Agate (including Moss Agate), Jade, Ruby, Jasper, Bloodstone as well as Star Sapphire. Or you can take the time to travel and find opal at Lightning Ridge in NSW, Austalia, topaz in Beechworth, Victoria or hunt specimens the quartz regions in Wave Hill in the Northern Territory of Australia.

Legend has it the Hope Diamond came from the eye of an idol in a temple on the
coleroon River in India. If that is so, one can only conjecture that the eye
must have had a mate, but the fate of "the other eye" has never come to light.
It would not be the first famous diamond that started it's notoriety in a
religious idol. The Idol's Eye, the Eye the Goddess, the Heart of the Goddess
and the Orlov came from idols, according to legend. Tavernier purchased the
stone and smuggled it to Paris, where he later sold it to King Louis XIV. It was
cut there into a triangular-pear-shaped stone weighing 67.50 carats, and was
then known as the French Blue.

The chief thing you need to consider is stone color. You want the stone that is as close as possible to the pure spectrum colors. We are talking about violet, orange, yellow, green, blue, and red. The prices of very dark are very pale stones are lower than the vibrant colors.
Cut is one of the all-important 4Cs and factors into appraisal of diamonds but gemstones as well. An excellent cut will highlight the pure color of the stone, lessen any inclusions and show off its symmetry and proportions. One excellent method to determine the precision of its cut is to check how evenly 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 inside the gemstone. That will make the gem seem washed out and windowed.
Gemstone clarity is our next factor. When we talk of clarity it relates to the absence of flaws or blemishes inside the stone. A gemstones that is normally found to be clean is obviously worth more. To determine the flaws not seen with the unaided eye requires a gemstone loupe or gemstone microscope. Serious hobbyists will employ an inexpensive 10X gemstone or jewelers loup for viewing stamps, coins, beads as well as gems.
Next on the agenda is the duo of weight and size. Due to their nature gemstones can vary greatly in density and specific gravity. Size and weight are not necessarily equal from stone to stone. If you have a diamond that weighs 1.00 carats an equal sized Sapphire would weigh more than 1.20 carats. An emerald stone would be about 0.95 carats and an Alexandrite gem stone would came in at 1.23 carats.
Getting involved in collecting gemstones can become an enjoyable pastime and also rewarding in the long run. You don't need to spend a lot of money and yet you can end up with some very beautiful stones. Many people love to take vacations 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 Opalton, Yowah, Queensland, Austalia, topaz in Beechworth, Victoria or check out the quartz regions in Cloncurry in Queensland, Australia.
