.95 grams, Rosy gold color, testing 6ct. Has a bit of wear- it's been on a chain so long that one side is slightly thinner than the others. Lovely history. There is a nearly imperceptible pit in the metal that is only visible under magnification. Would have originally been used to connect decorative fobs to a watch chain; we use them for putting collected charms on a necklace. 9/16" diameter, c. 1850.
