Beautiful cobalt blue with silver overlay Murano Venetian glass desk set is from around the 1950's. There are three pieces that have a variety of uses. Overall size of biggest piece that could be used as an cigar ashtray is 6" in diameter and 1 1/4" tall. The second piece that I believe is an inkwell is 3 1/4" in diameter and stands 2 1/2" tall without top. It has a very small chip on the bottom that is not seen unless you look at the bottom. The third piece 2 1/4" in diameter and stands 2" tall. You could use them all as paperweights since they are made from a very dense and heavy glass. I am not sure if they have a "silver deposit" or "silver overlay" on surface. I have cleaned one of the pieces and it does shine. Check out the pictures on this lovely set that plays with light and has the true Italian artistic tradition and heritage.
