James Tassie Gem Catalogue.
James Tassie (1735–1799), the Scottish sculptor and gem engraver, developed a way to make impressions of gemstones in plaster and coloured paste. This process made it possible for less wealthy collectors to collect gems. He became most famous for his portrait medallions and gemstone reproductions. These were highly sought after by 18th century collectors, and were used for display.
Tassie received commissions to duplicate many famous gems, both ancient and modern. At the time of his death, approximately 20,000 Tassie pieces were in existence. The total number of impressions which he made is considered to be much higher. Tassie seems to have been a perfectionist, destroying the impressions that did not live up to his high standards!
April-June 2017 the Library held an exhibition on James Tassie and the gem collection.
