Three different original antique Colonial cut lamp or chandelier prisms. All three sold together—3 different sizes. I couldn't match these with others I have.
One is 4 1/2" long and just short of 1" wide. One small nick in the top left corner.
Two prisms are 4" long. One is 1" wide, and the other is just short of 1" wide. The 1" wide one has a few tiny nicks on the edges. The other one has a tiny nick on the top corners.
 
They all look good. The nicks will be hard to see when hanging. I found these at an estate sale of an antique lamp and chandelier dealer.
