Gem-quality pink-orange euclase was discovered in Bahia, Brazil, in 2015-2016, but did not enter the international gem and mineral trade until mid-2018. There has been limited production to date from two different occurrences, located about 30 km apart, with an estimated production of less than 1 kg total from both sources. Although the pink-orange euclase from each occurrence has distinctive internal features, crystal morphology and colour zoning--allowing rough or cut stones from each locality to be readily separated from one another--their gemmological and chemical properties are similar, indicating they probably formed in a similar geological context. Some notable internal features exhibited by samples from the second reported occurrence include curly/woolly 'fibres' and associated circular/cylindrical inclusions. The unusual pink-orange colouration of this euclase is due to traces of Mn3+. [ABSTRACT FROM AUTHOR]
