Ooh, la la...nothing like vintage French jewelry! This comes from the French house Mauboussin. It's fully hallmarked, serial number, etc. (Shown in one of the photos)

It's crafted in luscious 18K yellow gold with a sparkling citrine in the center. To be honest, it's the first citrine piece I've purchased. I just love it!

I also think it's a great stacker. In the last image you can see it stacked with a Cartier band, which is sold separately.

This beauty is a size 7.25 and weighs 11.35 grams.
