Silber & Fleming, and one or two other sources, show similar shaped pieces as jelly or sweetmeat dishes - date wise these were popular in the second half of the C19.
I'd agree the stippled background and very curvaceous design suggest 'Lacy' - and although could be 'probably French' - equally likely to be from several other sources, including the U.K.. although apparently we made very little of the stuff. Are you sure they're lead glass?
