There might be many details on this piece - it is doubly terminated, free of damage, gemmy and lustrous - but to getting to the point: It's all about the color here! A blazing raspberry red that is visible even at low light and fills the whole crystal with its grace. At the termination this color gets an orange tinge. The backside of the tourmaline is covered in sparkling crystals that add a very nice effect. Very beautiful and catchy from the famous find made by Ailton Barbosa in 1978. This piece has a remarkable provenance, as it has been part of the collection of P. D. & Ann Sams. The label is coming with the piece.
