Here's a prism embossed CD 121 Hemingray / Patent May 2 1893 glass telegraph Insulator. Aqua with light milky swirls. Prism embossing dates this from about 1895-1901. Best swirls are to the front, and I HIGHLY SUGGEST this piece is best displayed in bright sunlight or base lit.

Has a dome side small BB ding as seen in the pictures, about 4-6 pencil lead point fleabites, 1 drip flat removed, and 3-4 drips slightly flaked.
