some references to this lamp note it as Leucos Murano
while Leucos notes on their website they were manufacturing Murano tiles, they are located on the mainland, not the island
the owners are children of original Murano glassmakers but it is confusing. Leucos is extremely well-known in the premium lighting industry so it almost does not matter if it is Murano or not.
however it would be fantastic if somebody here on the forum could share their knowledge / view
I also bought another famous Leucos design last week, will post later
