Duration: 2.5 months

Introduction:

The Gemology course has been specifically designed for anyone who may be interested in the study of gems and minerals.  This 2.5 months course includes theory and practical hands on training. It covers a wide variety of gems commonly encountered in the gem and jewellery market like Rubies, Sapphires, Amethysts, Topaz, Quartz, Pearls etc. including some rare gemstones too.

Starting from the rough ‘mineral’ the course goes right up to teaching the fundamental character of gems and the most modern techniques used for their identification. This course is designed for persons interested in jewellery designing, sales professionals or making one a more confident buyer.

Gemmology is the science dealing with natural and artificial gemstone materials. It is considered a geoscience and a branch of mineralogy. Some jewellers are academically trained gemmologists and are qualified to identify and evaluate gems.

The first gemmological laboratory serving the jewellery trade was established in London in 1925, prompted by the influx of the newly developed “cultured pearl” and advances in the synthesis of rubies and sapphires. There are now numerous gem laboratories around the world requiring ever more advanced equipment and experience to identify the new challenges – such as treatments to gems, new synthetics, and other new materials.

Gems Identification

There is a point where identifying gems becomes an art. The final determination is made by human observation, combined with knowledge and experience, rather than measurements taken with precision instruments. This is especially true when it comes to separating natural from synthetic gems. Most measurable physical and optical properties of a synthetic ruby will be identical to those of its natural counterpart. Distinguishing natural and synthetic stones involves observing inclusions in gems through a microscope. In some cases, this is simple and straightforward. In other cases, this requires judgment based on experience.

Crystallography:

  • Crystallography – study on crystals growth, formation of atomic lattice, Gemstone habits, crystal system based on its elements of symmetry, twinned crystal.
  • Rough gemstone identification, Gem deposits, knowledge of manufacturing process.
  • Origin and structure of gemstone.
  • Crystallography is useful in phase identification. When manufacturing or using a material, it is generally desirable to know what compounds and what phases are present in the material, as their composition, structure and proportions will influence the material’s properties. Each phase has a characteristic arrangement of atoms. X-ray or neutron diffraction can be used to identify which patterns are present in the material, and thus which compounds are present. Crystallography covers the enumeration of the symmetry patterns which can be formed by atoms in a crystal and for this reason is related to group theory and geometry.

Crystal Quartz:

Ordinary yet extraordinary, colorful and clear, Quartz crystals are the most common and abundant in the world, comprising the largest and most diverse family in the mineral kingdom. “From ancient times to the present day, quartz crystals have been a source of Light to mankind. Highly valued by spiritual leaders and healers as well as scientists, the unique attributes of quartz have played a key role in mankind’ evolutionary development. For all its variety, when most people speak of “crystals”, they are usually referring to Rock Crystal (Clear Quartz), the six-sided prisms of pure light and energy known as the Perfect Jewel. In its sparkling light is contained the entire color spectrum.

Mine Identification:

Our gemstones and minerals traveled across the world to become a part of your collection!  We have rocks in our mining rough that were mined in countries as far away as Brazil, Peru, Mexico, India, and Madagascar.  We hope you enjoy learning about new treasures.
