Andrew Grima (1921–2007) was the figurehead of British modernist jewellery. From the 1960s his abstract, textured gold — often built around raw, uncut crystals and unusual mineral specimens — broke completely with traditional design, won royal patronage and Duke of Edinburgh awards, and is now among the most sought-after of all post-war makers.
What is Andrew Grima jewellery?
Grima is defined by abstract, sculptural 18ct gold with a nuggety, bark-like or molten texture, frequently set with raw uncut gemstones, slices and natural crystal specimens — tourmaline, citrine, agate, watermelon tourmaline and more — across brooches, earrings, rings and pendants. Pieces are signed Grima and carry British hallmarks with a date letter; some bear the "About Time" or royal-warrant context.
