This is a set of four large and one medium French pendalogue cut lead crystal prisms, all in the same shape. The large ones are 6" x 2 3/4" and the smaller one is 3 7/8" x 1 7/8." These measurements do not include the octagon crystals wired at the top of each piece. That would increase the length to 7" and 4 1/2." One of the large crystals has a large flat chip on the back, and one has a small chip on the rim, right hand side about half way down. Please see my other items for more vintage prisms. MBR.
