Description

A fantastic assemble of steel-blue tourmaline set on a small base of lustrous, snowy white cleavelandite with minor violet lepidolite. The top of the elongated, glossy tourmaline crystal is sharp end-pointed and shows a small area of greenish zoning. You can see the blue color even under daylight, no lamps are needed! Like 99% of al specimen in this dimension from Pederneira also this one is repaired, well done in the lab of Pezotta. The assemble is simple breath-taking, couldn´t be more aesthetic and this dimension is really impressive - a center piece for each tourmaline collection.
