A Complete Four-Day Gemmological Workout

This four-day workshop covers a variety of subjects ranging from how diamonds and coloured gemstones are graded, the twelve primary gemstones used in the trade to the fluid and challenging area of gemstone enhancements and treatments.

The workshop starts with the grading techniques used to assess the quality of both diamonds and coloured gemstones. Topics covered include the 4 C’s (colour, clarity, cut and carat weight), how they are measured and assessed, how to describe the colour of a coloured gemstone, the various colour grading systems currently used by professionals, the clarity classification of coloured gemstones based on their geological environments, and how cut is assessed.

From there, we move onto the twelve primary ‘Birthstones’ (garnet, amethyst quartz, aquamarine, diamond, emerald, pearl, ruby, peridot, sapphire, opal, topaz and zircon) giving an overview of their physical and optical properties, principal sources, how they are produced synthetically, how they are valued, helpful buying tips and basic testing methods.

The workshop concludes with a complete overview of the enhancement and treatment of gemstones. Topics covered include heat treatment, surface and sub-surface diffusion, lead glass fracture filling, flux assisted partial fissure healing, glass fracture filling, cobalt doped glass filled sapphires, clarity enhanced diamonds, HPHT, quench-crackling, surface modifications, coatings and foil backs, laser drilling, and irradiation.

The workshops are being offered in Mallorca, Spain (September 28th to October 1st, 2017) or in London, United Kingdom (November 6th to 9th, 2017).
