Overview A fabulous example of Andrew Grima work from the height of his career. The rough triangular shaped amethyst crystal sparkles and glistens in the light, reflecting deep, regal purples and fresh lilacs. Held organically with three 18-carat yellow gold textured 'claws'. Textured gold such as this was a style used abundantly by Grima throughout his work, especially in the 1960s and 1970s. English hallmarks for 18 carat gold on the rear frame with the makers mark 'HJCo'. An Iconic British jewel. Date letter for 1964.
