The Abernethy Pearl aka 'Little Willie' is known to be one of the most perfect, spherical, natural Freshwater Pearls in the world.
The Abernethy Pearl was discovered in Scotland's River Tay — home to the freshwater mussel Margaritifera Margaritifera — in 1967 by professional pearl diver William Abernethy, for whom the pearl is named. The exquisite pearl was shortly thereafter nicknamed in honor of its discoverer and has since become also widely known as 'Little Willie.'
Famous for its high quality Freshwater Pearls since ancient times, historians believe it is because of this reason that Roman Emperor Julius Caesar invaded Britain, with hopes of controlling the trade of Scotland's Freshwater Pearls.
The Abernethy Pearl is an exceptional Freshwater Pearl, one of the most spherical ever discovered — a very rare occurrence in natural Freshwater Pearls. The pearl is of medium size, weighing 11 carats or 44 grains, and; though, the actual diameter of the pearl is unknown, it is said to be comparable to that of a marble.
Not only exquisite in size and shape but also luster, color and surface quality, Little Willie's striking luster is almost equivalent to that of an Akoya Pearl; its color, a pink-ish white tone — a white hue with slightly pink overtones — and its surface, of blemish free skin.
The Abernethy Pearl is currently on public display at Cairncross Jewelry Store in Perth, Scotland.
