I was lucky to find these special beads some time ago: dark coffee-brown and faceted.
I think they are venetian, in any case they are old Beads.
They have a shimmering appearance and a special effect.
They look definitely brown, but when you hold them against the light, they have a glimmer of emerald....
They are most effective crafted simply and pure. There are not too much beads left, and so I´m very stingy, using them!
