Antique Cartier Miniature Silver Enamel Clock
This jewel is a true Objet d'Art. This miniature clock was made for Cartier by Louis Kuppenheim, The case at least has the Kupenheim marks, a firm out of Germany from the second half of the 1800s into the early 1900s that made amazing pieces of silver and enamel. The case encloses a Swiss 3/4 plate miniature clock movement with a face branded for Cartier. This would be the quality level of something Cartier would import and handle during that time. Unfortunately the face has darkened over time and my photos show some fuzz from the case but that does not detract from the stunning work on this clock.

Gold standards in most countries are 10k, 14k, 18k and 22k.
These are averages and while a piece may be marked 14k please be aware that the
gold content itself could have a variance of up to 1.5k. This means something
marked 14k could be in a range from 12.5k to 15.5k. This is especially
true of vintage pieces as technology wasn't as precise. With gemstones, we
guarantee everything described as a diamond has been tested. With colored
gemstones however, particularly when small secondary stones, we make our best
efforts to be accurate in the description but there could be some variance as
to what the stone is. Colored stones of nominal value and semi-precious
stones can't be accurately tested unless sent to an organization such as
GIA. If you have any concerns about colored stones in a specific piece,
please contact us before bidding.
