This rare sugilite specimen displays exquisite, fibrous royal purple crystallization across its main display face in patched and mottled patterns. Sugilite is increasingly scarce and highly sought after, making this a serious collectors piece.
Sugilite is a very rare cyclosilicate mineral that typically forms in massive, microcrystalline aggregates and dislays pink to deep lavender purple tones, caused by the presence of manganese, with some specimens also showing impressive chatoyancy or mottling where chalcedony is present. It is most commonly opaque, though some scarce specimens may also be translucent (referred to as 'gel sugilite'). It is also one of the most incorrectly pronounced mineral names, with many pronouncing sugilite with a soft 'g', as in 'gene', when it is correctly pronounced with a hard 'g', as in 'geese'. This mineral is also known as 'wesselite' because exceptional, translucent, gem-grade material is found in the Wessels Manganese Mine near Hotazel, South Africa. The finest, pure purple sugilite commands high prices and is considered one of the greatest purple gemstones in existence.
Sugilite in History
Sugilite was first found in Japan in 1944 as a brownish-yellow rock-forming mineral and named in 1976 by Nobuhide Murakami in honour of the petrologist Ken-ichi Sugi. An exceptional deposit was then later also found in 1979 in South Africa forming in attractive rich, bright pink and lavender purple colours, and this variety became highly sought after for use in ornamental carvings and jewellery.
