Sophisticated Synthetics and Gemstone Enhancements:
Bring your knowledge of the important gemstones up to date! Emeralds, sapphires, rubies and diamonds are valuable gems for which many simulants and synthetic counterparts exist, and which are frequently enhanced.
The primary focus of these workshops is on the nature and occurrence of inclusions within the various "sophisticated" synthetics, and the detection of new methods of enhancement. Participants will have a chance to practice the various techniques and tips provided for distinguishing naturals from synthetics and for detecting enhancements using gemmological equipment.
There are no prerequisites for this workshop, however a gemmological background or trade experience would be an asset.
An intensive, hands-on course which will provide knowledge and skill in the grading of colourless, round brilliant cut diamonds. Please note: this course focuses on the diamond grading process, not the identification of diamond and/or its simulants. All necessary major equipment is provided, but students should bring their own pocket instruments (which are available at reasonable cost on-site). Required course textbook may purchased separately. Class size is limited to a maximum of 8 students.
This three-day workshop will benefit gem trade professionals, gemmology students and enthusiasts alike.
