Gemmology : Introduction
Gemstones have intrigued us throughout history and are reputed as symbols
of wealth, power, healing, and love. They are desired for their beauty,
rarity, value, durability, tradition and portability.
Gemmology is the scientific study of gemstones. It is
a branch of mineralogy that is concerned with the study of gem materials,
including identification and testing methods, cutting and polishing synthetically
manufactured gems, precious metals and alloys, their sources and origins
and grading and appraising. Those interested in possessing gems for their
value should have an idea of Gemmology to distinguish one gem from another
The first step in learning about gems is its categorization. The next
step is to learn the terminology of gemstones and then their physical
and optical properties, and how those properties are used to identify
gems. After getting the background one can proceed into gem identification. Studies
relating to this field are gem cutting, sorting, grading, valuation and
identification of gemstones, fashion, computer pattern designing, jewellery
making, consultancy regarding stones, selling etc.
While Gemmologists study the quality, characteristics
and value of gem stones, Jewelers typically do the handiwork required
to produce a piece of Jewellery. Gemmologists identifies the gems
and advises the jeweller about the compatibility of gems to particular
metals. In Jewellery, identification is one of the key element of business.
Some rubies and garnets sometimes look alike, but their values are considerably
different, only a Gemmologists can easily identify the difference and
know its physical characteristic and value.
In India the Gems & Jewellery scenario is undergoing a positive change
with diamonds and stones like Tanzanite, Tourmalines, Peridots dominating
the consumer preference. At the same time traditionally preferred Gems
like Rubies, Sapphires and Emeralds have maintained a consistent position.From
trade point of view Gems & Jewellery has been one of the biggest foreign
exchange earner for India. It is therefore, highly necessary that people
associated with the trade, receive training and carry out the operations
scientifically and professionally so as to achieve greater success.
