This listing is for a very nice onyx signet cabochon/ gemstone, inlaid with the letter I in a cool calligraphy script. I believe it is from from a class/ signet ring or similar piece of jewelry. The I is inlaid, whether with gold or paint I am not sure. Overall a very nice piece, it has some slight wear, but none of the usual major damage from removal- but does have some light wear to the face of it. Please see photos for exact details. Great piece for jewelry making, artisans, collectors, or holiday gift giving!
