Stalattite Oro is one of the most precious and esteemed onyxes. The blocks of Stalattite Oro are extracted in Italy. The slabs are characterised by the golden-caramel background with white veins of various thickness. The blocks of Stalattite Oro are very fragile, and usually spacial resin treatments are necessary, before the cut, in order to avoid the loss of some slabs. Also the slabs have a very crystalline structure and so they are very fragile. Therefore the slabs are always resined in order to fix some micro-cracks and increase their resistance. Ziche resins all the slabs of Stalattite Oro three times with vacuum epoxy resin. This high quality process is only possible by using the most modern technologies, and allows to obtain slabs with a perfect structure, free of any kind of cracks or defects. The Stalattite Oro slabs can then be polished. This Onyx is commonly chosen for prestigious details, usually because of its transparency in settings where the tile can be back-lighted.
