Description

The Hyal Quartz or Crystal of Rocca is pure and crystallized silica, perfectly transparent and colorless, which usually comes in crystals of elongated bipiramidal dress ragguppati in spectacular druses.

The geometric structure of the rock crystal is practically unique in the gemmological world: the well formed crystals, especially when they are grouped together in geodes or druses, are sought after by collectors.

With Serpentine means a group of minerals belonging to phylaxis, these are specifically magnesium, iron and nickel hydrates, present only in solid form and never in crystals.

The prevailing color is the green with different shades.

The Rose Quartz is a variety of quartz that has a pink coloration, sometimes with reddish hues.

The color is given by the presence of traces of metallic oxides, mainly of manganese, iron and titanium titanium titanium titanium. In rare cases of fibrous crystalline inclusions give rise to the phenomenon of'asterism, with six-ray stars similar to those of the corundum.
