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.‎ Both small and large Pyrite are available in this delicate DeOpale brass finish by De Castelli.‎ All Bomma products are hand-made from mouth-blown lead-free crystal.‎ Therefore any small bubbles, non-melts and irregularities in the glass are both proof and a characteristic feature of this traditional craft.‎Cable transparent 2,5 m Glass mouth-blown lead-free crystal in clearMounting brushed brassMetal sheet top deopale brass (=manually oxidated brushed brass)Protection IP 20Nominal voltage 220-240V / A.‎C.‎ 50 hz (EU)110-120 V / A.‎C.‎ 60 Hz (USA)Class III.‎ EU / II.‎ USALIGHT SOURCEType G4, 1,2W LED, 100 lmBase G4 (EU) / G4 (USA)Voltage 12V, ACTemperature 2700 KColor index RA 90+ Dimmable in constellations.‎Single pendant is non-dimmable except ULTRANSFORMERPrimary 100–240V, 50/60 Hz, 0,04ASecondary DC 700mA (0,5V–4V) 1×3W
