Pyrite – the golden firestone in the shape of a perfect cube now in DeOpale brass finishing by Italian manufacturer De Castelli. Both brands excel in handmade production while sustaining the highest quality standards. BOMMA and De Castelli jointly introduce Pyrite in special edition. The surface of this hand-blown crystal cube is encased from three sides in a DeOpale brass element. This exquisite brass fitting gains particular chromatic effects, thanks to the manual oxidation of brass, such as the light games of the fire opal characterized by a yellow background with reflections that can be particularly vivid and bright, changing in iridescent tones from red to orange.
