How To Start Gemstone Collecting


By Lee MacRae


Gemology is the science, art and profession of identifying and evaluating gemstones from natural diamonds to loose gemstones. Many people take up gemology as a passionate hobby. They become very interested in starting to collect loose diamonds or loose gemstones. You'll even find some that like to visit various locations close by or even in other countries to look for rough gemstones. Some even tumble or learn to cut their own gemstones. If this hobby interest you read along as we show you the things you should know to start this hobby.


To begin with 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.


To start with, an important aspect in gemstone evaluation is color. Gemstones are the most intensely colored natural materials you can find. These materials are so related to their color that they've even had their names combined with associated colors. Without a doubt you will recognize sapphire blue, ruby red, jade green, aquamarine, emerald green or turquoise. Gemstones are valued much higher the closer they come to the natural spectral colors of red, orange, yellow, green, blue, and violet. They become less valuable the farther they deviate from the pure natural color.


How a stone has been cut is the second most important value determination to consider before a purchase is made. The precision of the cut is the factor that determines the amount of light the gemstone stone will reflect. It will ultimately determine the brilliance of the stone and its final value.


Another factor to look at is the clarity of the gemstone. This is talking about the purity of the stone or the absence of internal inclusions, internal particles or spots within the crystal structure. Without a doubt, zero flaws are hard to find and make your stones very valuable.


Next thing to look at is the duo of size and weight. Due to their nature gemstones vary and specific gravity or density. Weight and size are not equal for each and every stone. Take the example of a diamond that weighs 1.00 carats and a sapphire of equal size would weigh 1.20 carats. An Emerald of equal size would be approximately 0.95 carats while an Alexandrite gem stone would came in at 1.23 carats.


Collecting various 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 Emerald, Tiger's-eye or Tourmaline and then try others. The opportunities are seemingly endless. And if you like to save money but love vacations you can find gemstones for yourself instead of buying. Take the example of the United States. In Idaho you'll find Garnet, Opal, Agate, Obsidian and Sapphire.

The Mandalay Ruby. This 48.019-carat cushion-shaped ruby was offered for sale by
Sotheby�s New York on October 18th, 1988 but received no bids. Sotheby�s implied
that it may have been the 47-carat J.N. Forster Ruby, which was found sometime
before 1877, but this is quickly ruled out. Two large Burma rubies brought to
England in 1875, weighing 37 and 47 carats. These were put on the market by the
Burmese royal family and were later recut by Forster to 32 5/16 and 39 9/16 ct (
or 38 9/16 ct); one sold for �10,000, the other for �20,000, respectively.
Sotheby's also implied at the same time that it could be one other famous yet
unnamed ruby weighing 46� carats; oblong in form (probably cut); mounted in a
brooch with four brilliant-cut diamonds and sold (or bought in) at Christie's of
London on May 7th, 1896 for �8000. Many doubt this version of its history as
well.

E.W. Streeter, in his book Precious Stones and Gems (1892), describes a number
of fine sapphires. One of these was in the collection of the Mus�e au Jardin des
Plantes, in Paris, and weighed 133.06 carats. The same stone was also described
by Sourindro Mohun Tagore in his classic, Mani-M�l� (1879, 1881), referring to
it as the Wooden Spoon-Seller�s Sapphire, in reference to the poor man who is
said to have found it in Bengal, India. Streeter said it was without flaw. This
is undoubtedly the same stone that resides today in Paris's Museum of Natural
History, for it is of a distinctive lozenge shape and possesses only six facets,
appearing like a huge sapphire rhomb. It is indeed nearly "without flaw,"
containing only one small feather and crystal inclusion, and is possibly of
Burmese or Sri Lankan origin. According to the museum's H.J. Schubnel, the
sapphire actually weighs 135.80 carats. In the museum it is known as the Ruspoli
Sapphire. During the 17th century, a Roman prince named Ruspoli sold this
sapphire to a salesman, who in turn, sold it to King Louis XIV sometime before
1691. At that time it was the third most prominent gem in the French Crown
Jewels.

To be classified as a gemstone, a material must possess three qualities: beauty, rarity and durability. Beauty can be measured by the gemstone�s color, clarity and cut. Rarity is determined by the scarcity of the gem�s occurrence in nature or in the marketplace. And durability is based on the hardness, toughness and stability of the gem.
