Taken directly from an old chandelier built in 1960s. Collection of 14. Clean and free of chips and scratches. From top of 2-piece prism to bottom is approximately 2 3/4 " and across widest part of prism is about 1 1/4". Be creative. These crystal prisms are just waiting to be re-purposed! Metal hangars may need to be replaced, depending on how you intend to use them. Lovely facets can really bend light in rainbows of sunlight in right circumstances.
