These are six antique Victorian black glass buttons with an incised lizard or reptile on top. The buttons are not marked. They are shank buttons. There are five incised flowers along either side of the lizard. The lizard and flower incisions are filled with gold. The lozenge shaped button measures 3/4 of an inch by 3/8 of an inch. The buttons are in very good condition with no chips or cracks that I could find. The buttons have not been cleaned or polished. Please let me know if you have any questions. Thanks for stopping by.
