Choudhary G. (2015) A Shattuckite Briolette. The Journal of Gemmology, Vol. 34, No. 7, pp 566-567

A deep intense blue briolette of shattuckite was examined, which also had few areas of malachite.  The specimen was identified as shattuckite on the basis of Raman spectroscopy, and without this technique it could have been mistaken for azurite.
