We welcome with enthusiasm the trend for marble lights. Serafini Marmo Luce is young company currently working in calacatta marble (above) and travertine (below)
Calacatta marble is very similar to carrara marble -- it looks pretty much the same and it is also mined at Carrara (where the village square is paved with marble and where, after a busy day at the marble face, the miners go back to the bar to eat the finest lardo and drink English beer). We are indebted to fellow blogger Houzz for a useful post Carrara vs Calacatta Marble: what is the Difference? Calacatta is rare than carrara and is considered a luxury stone.
The best way to bring out the quality of the material is to shine light through it. By cutting into the marble more in some places than others, the translucency varies:
Because travertine is holey, its effect is different, but very lively and interesting:
...whilst in a picturesque medieval barn in Germany, Georg Eisenhut of Gio is using carrara and other marbles to make glorious long, linear pendants. The light source is halogen, so a proper light is cast downwards onto the table (or whatever) beneath, and these lights glow in a way that draws people across a crowded room like moths to a lamp. Ideal not just for rectangular dining tables and snooker/pool/billiards tables, but also for reception desks in hotels. Here is his Carré X in carrara marble
and a tiny matching wall light, Pix, also in the carrara marble version:
In this case, the structure (i.e. the bit that is not the translucent globe), which would normally be metal or something, is made of marble. It took them a long time and much searching to find a marble with graining that would work in such a small piece. But we saw Mass Light at Maison et Objet in January 2012 and it looked very good. Several can be hung together:
