In the last two decades there has been a proliferation of certification, not only for diamonds but for gemstones as well. There are five 5 major laboratories which grade and provide reports on gemstones.

  • Gemological Institute of America (GIA)
  • American Gemological Society (AGS) is not as widely recognized nor as old as the GIA but garners a high reputation.
  • American Gem Trade Laboratory which is part of the American Gem Trade Association (AGTA) the largest trade organization of jewelers and dealers of colored stones.
  • American Gemological Laboratories (AGL) which was recently taken over by “Collector’s Universe” a NASDAQ listed company which specializes in certification of many collectables such as coins and stamps.
  • European Gemological Laboratory (EGL).

Although certification can provide certainty and clarity, each laboratory has its own methodology to evaluate gemstones; grading experience is different and depending on the cert required each lab approaches these issues differently. Consequently a stone can be called “pink” by one lab while another lab calls it “Padparadscha”. One lab can conclude a stone is untreated, while another lab concludes that it is heat treated. Countries of origin has sometimes been difficult to find agreement on due to the constant discovery of new locations. Gem labs need time to study them. Moreover determining a “country of origin” does not have the exact scientific methods at its disposal as other aspects of a gem (such as cut, clarity etc.)

Gem dealers are fully aware of the differences between gem laboratories and will make use of the discrepancies to obtain the best possible cert. One such example is to make use of the differences in “Country of Origin”: a sapphire from Kashmir (celebrated for its cornflower blue color) commands four times the price of the same stone from Ceylon and twice the price if the stone were from Burma.

An Overview of Gemstones

A gemstone usually refers to a rock or mineral that is used in jewelry or as a collector’s item, usually after it has been polished, cut or faceted.

Gemstones are classified through several ways. They may be grouped according to chemical composition — for example, rubies are made of aluminum oxide and diamonds are made of carbon. If they are crystals, they may be classified using the crystal system, which divide gemstones into cubic, trigonal or monoclinic. They are also classified according to habit, which refers to the shape of the stones. It’s also possible to group gemstones according to species — for example, the mineral species beryl would include such gemstones as emerald, aquamarine, bixbite, goshenite, heliodor and morganite.

Buying a gemstone can be an absolute joy. Imagine the thrill of being surrounded by a roomful of precious gems, with colors that dazzle and captivate. Over 30 types of gem varieties have been identified, not counting those rare, singular gemstones that show up once in a while and defy category. Some of these gemstones have decorated and adorned the earliest civilizations of man, while others are recent discoveries but nonetheless as impressive as their forebears.

Emeralds are the most popular gemstones in the world and have been esteemed since ancient times. They are a dazzling green all over, alternately shiny and intense to the eye. The highest-quality emeralds are more coveted than diamonds, a little known fact. They were named from the word “esmeralde” which is Old French for “green gemstone.” Their rich history dates back to the times of great ancient civilizations like the Incas and Aztecs. Its roots are buried deep in the jungles of South America where the rarest of emeralds can still be found.

The ruby is the gemstone that best represents love and vitality, passion and intensity. The ruby has long been regarded as first among gemstones, their bright red glow that conveys strength and warmth. These qualities made the ruby the most valuable gemstone for centuries, a royal favorite of emperors and kings.

Often compared to the blue sky in literature and history, sapphire has as many shades as the sky has hues. Legend has it that early man actually believed that the sky was made of one big block of sapphire and that the earth was simply a thorn on its side. Among emotions, Sapphire is associated with noble feelings of harmony, friendship, loyalty and sympathy. And since blue is the favorite color of about half the world’s population, sapphire’s appeal and popularity worldwide is not surprising.
