INTERNATIONAL AMBER ASSOCIATION REPORT

AMBER TRAINING COURSES –

identyfing amber and immitations

In

By Michał KOSIOR May 2014, the IAA ran gemmological testing exercises with amber, selected natural resins and imitations.

The workshop was conducted by Jacek Ożdżeński,

certified gemmologist of the Deutsche Gemmologische

Gesellschaft and the PTGem Polish Gemmological Society, expert member of both DGG and PTGem, expert of the SRJ Polish Association of Jewellery Experts and an amber expert of the International Amber Association. Each participant was working at a workbench fully equipped with an individual source of white light, magnifying glasses, tweezers, a microscope and other necessary devices. The exercise was to review more than 200 natural specimens, preparations or finished products made of amber, resins or imitations, which were simultaneously displayed on screen with a discussion of their typical features. In part 2 of the exercise, every participant received 100 such preparations and cabochons each, for individual practice. The exercise was fully focused on the practical recognition of the materials, with a limited time dedicated to theory. The aim of the workshop was to present the features which are typical of various kinds of Baltic amber, other fossil resins and the most common imitations. The knowledge of testing methods and properties will allow the participants to preliminarily distinguish amber from its imitations or treated amber. It is also the basis for the further development of know-how and skills based on those already gained. This is the first workshop exercise that the IAA has offered to participants. So far, theoretical courses for amber sellers were carried out, with topics including geology, chemistry, history, biology and contemporary methods of amber treatment. The IAA is planning to extend its training offer to include both amateurs and professionals.
