Abernethy_pearl
The Abernethy pearl, also known as the Little Willie pearl, is a 43.60-grain (2.825 g) freshwater pearl[1] named after William Abernethy (1925–2021), who discovered it in Perth, Scotland, in the River Tay in 1967.[2][3] It is also known as Bill's pearl.[1]
The Abernethy pearl was produced by a mussel belonging to the species Margaritifera margaritifera. It is spherically shaped and coloured white with a slightly pink overtone.[2][4]
The pearl was reportedly valued at £10,000 in 1967 (equivalent to £164,596 in 2019).[5] It is now displayed at the A&G Cairncross in Perth.[6]
