Gem Stones have fascinated man since the beginning of time. Even prehistoric man was drawn to the glimmer of shinny pebbles in the sand. Gem stones are natures rarest products but to be considered a gemstone they must possess three attributes, rarity, color, and of course beauty.
A gemstone is a piece of mineral that is used to make jewelry however certain rocks such as lapis lazuli and organic material such as amber and jet are classified as gem stones even thought they are not minerals. Most gemstones are hard making them ideal for jewelry making.
The traditional classification of gem stones dates back to the ancient Greeks, when they made the distinction between precious and semi precious stones.
This distinction reflects the quality, and rarity of the stones amongst the most well known of all precious stone are the diamond, ruby, sapphire, and emerald.
Nowadays such a distinction is no longer made by the trade because many gemstones both precious and semi precious are used in even the most expensive jewelry.
The value has come to rely on the brand name of the designer, fashion trends, market supply, and treatment of the stone itself.
This being said diamonds, rubies, sapphires and emeralds still have a reputation that exceeds those of other gemstones.
There is no universally accepted grading system for gemstones but there are many factors that influence the value of gemstones. The most common ones are called the 4 c's - color, clarity, carat, and cut. These factors have an impact on most gemstones, but on some more than others.
A few gem stones are used in their natural crystal form but many must be cut and polished for use in jewelry. Grinding wheels and polishing agents are used to grind, shape and polish the smooth dome shape of the stones. Still others are faceted, a method which takes advantage by maximizing reflected light which is perceived by the viewer as sparkle this method is best observed in translucent stones such as diamonds and rubies.
Due to the rarity and expense of some gem stones labs have begun making synthetic copies of these stones such as cubic zirconia. These imitations copy the look and the color of the diamond but cannot copy the chemical or physical characteristics. Synthetic rubies and sapphires are very common and cost only a fraction of the price of the natural stone making hem highly desirable.
Some seek stone for their beauty, some for their rarity, and some hold a much deeper meaning. Stones have been sought after for the healing properties that they posses. Folklore about stones has been revered and honored for centuries in all cultures. Whether lab created or natural man is still mesmerized by the beauty of the gemstone.
History of gems
Even in antiquity as men gazed at the shapes of crystals, whose origins they could not begin to understand or explain, it is not surprising that it was thought that these fascinating formations held supernatural powers.
Fantastic origins have been suggested over the years for stones...rock crystal was ice permanently frozen by intense cold... hyacinth (a precious stone of the ancients sometimes thought to be the sapphire ) was produced by the earth's extreme aridity combined with the sun's powerful action... amber was thought to be a product of lynxes' urine and birds' tears.
In the Stone Age, primitive men became interested in gold, which was relatively easy to melt and to cast. From this the first pieces of real jewelry were made.
Silver and copper were mined during the Bronze Age and jewels, ornaments and cult statuettes were made from copper, bronze and rocks of unusually striking color or shape.
The ancient Egyptians commonly inlaid gold and silver with semi-precious stones such as carnelian, jasper, amethyst, turquoise and lapis lazuli.
A particularly popular jewelry item was the signet ring and many of the motifs used, such as the lotus, falcon, serpent and eye, were derived from religious symbols.
Scarabs, representations of the scarab beetle carved in stone, were also popular in ancient Egypt and Rome.
The Greeks made ornaments of plain gold until around 400 BC when a variety of gems and cameos (precious and semi-precious gemstones carved in relief on one layer with another contrasting layer as background) were used.
Roman jewelry was massive with ropes of pearls highly prized and Medieval jewelry included very large brooches.
During the Renaissance, men and women wore gold chains, jeweled collars, and pendants, often designed and sometimes even rendered by noted artists. Ornaments crowded with stones were worn to excess in the late 17th century . Jewelry was almost superseded in the late l8th century by decorative buttons, watches and snuffboxes, but the 19th century brought the revival of the bracelet and the cameo. When factory production of jewelry began, artistry declined and costume jewelry was introduced by Gabrielle Chanel in the 2Oth century. However, there has been renewed interest in hand-wrought jewelry since the craft revival of the 1960's.
Stones were also widely used in the production of seals, carved dies or stamps used to mark documents or objects with a sign of official origin or ownership.
Ancient seals were generally engraved with a design to be impressed on wax or damp clay.
In China, however, seals carved in relief were used with ink as stamps, representing an early form of printing.
In ancient Greece and Rome, seal rings and portrait seals engraved with the owner's likeness became widespread. Although the use of seals declined after the fall of Rome, it was revived during the l2th century and from then until the l8th century, heads of church and state and various civic dignitaries used seals carved with heraldic designs to stamp their documents.
Crystal balls have been produced -and highly prized -throughout recorded history.
The Japanese have the highest respect for rock crystal, which they consider to be the symbol for perfection and purity, and Japanese craftsmen have produced crystal balls for centuries... the perfect jewel cut into the perfect form.
The Japanese believe that the dragon is the supreme creative power and early thought was that rock crystal was formed from the condensation of the dragon' s breath.
Crystal balls from high-qualit rock crystal found in the Alps were highly prized in Europe as well, though for different reasons.
In Europe crystal gazing was used not only as an aid to foreseeing the future, but as a stimulus to the mind. Musicians, authors and even politicians have benefited from self-hypnosis induced by crystal gazing.
