There is! But it is for pictures only at the moment:
Dior Joaillerie (fine jewelry pictures only)
2nd haul - from their new fine jewelry Rose des vents series This is a bracelet - 18k rose gold, pink opal and diamond

There is also an old thread that we can post that in:
Dior Joaillerie
I saw this pic on instagram and wonder if anyone has more info on the long necklace and how much does it cost? Is it costume or fine jewelry? Does anybody know? TIA

I'll copy your post there.
