Lacroche frer. jewelry

I appeal to anyone who knows of the "Lacroche Frer." jewels.
Somewhere in France there would have existed a jewelers workshop, founded by the brothers Lacroche. But I can't find anithing about it.
On the jewel thers is a signature with the inscription "Lacroche Frer."
If there is anyone who knows anything more about these jewels or the workshop in France may always mail me at: arch-vision@ Sharing is sexy
