The Llanllyfni lunula (Welsh: Lunula Llanllyfni) is a gold lunula, found in Llanllyfni, Gwynedd, Wales but now held in the British Museum in London, England. It dates from 2400BC-2000BC.

The lunula is made of decorated gold and dated to 2200-2000 BCE and is one of the earliest gold ornaments from Wales.^[1] Other estimates suggest 2400-2000 BC of the Late Neolithic/Early Bronze Age.^[2] The lunula is the heaviest lunula from the islands of Britain and Ireland, weighing 185g.^[3]

Llanllyfni lunula. Weighing 185.4g (6.5 ounces) and measuring 24cm (9.5 inches) in diameter. This crescent-shaped ornament probably originated as a single rod shaped ingot and was expertly hammered into shape. The intricate decoration of zig-zags, lines and dots was then added using a fine-pointed tool and a copper or bronze punch. These designs are very similar to those used to adorn pottery made at this time.

It is likely to have been a ceremonial piece. Lunulae are common finds in Ireland and research evidence suggests that multiple Irish lunulae are made from Cornish gold. The decoration on the Llanllyfni lunula is similar to the decoration of many Beaker pottery vessels from Wales. This is a 'Provincial' type lunula with normal transverse end-plates and fine incised geometric ornament towards the tips of the horns.^[1]

The lunula was found in a bog of Llecheiddior-uchaf ffarm near Dolbenmaen in about 1869. A farmer noticed what he thought might be a yellow laurel leaf sticking out of some peat. Unsatisfied with his self-explanation, he later returned and unearthed the lunula in full.^[3][4]

The British Museum acquired the lunula in 1869 after purchasing it from a Griffith H Owen.^[2]
