Petalite
Mogok, Burma
A rare mineral, petalite generally occurs in pastel yellow although it is sometimes seen ranging from pink to colorless. It was discovered on the Swedish island of Ut Arfvedson by the Brazilian scientist, Jos Bonifacio de Andrada de Silva, while he was visiting Sweden towards the end of the 18th Century. The name "petalite" is derived from the Greek Petalon meaning 'leaf' and 'lithos' meaning stone referring to its leaf-like cleavage. The major sources for nice, transparent and facetable stones are Brazil, Namibia and Burma, with the present example coming from the classic Mogok, Burma source. It owes its desirability to rarity, and definitely deserves a place in collections, especially in larger sizes such as the present stone. Any specimen that weighs above 2.0 carats is considered rather large. Whether used as a collection stone or mounted as jewelry (the hardness is 6-6.5), it is sure to be a great conversation starter. The present stone has been faceted as a mixed, cushion-shape to best reveal its high degree of transparency and luster. Weighing approximately 13.64 carats and measuring 15.97 x 13.62 x 11.26 mm
