Jewelry Advise! Need to buy iconic item from the BRANDS i mention in post.

[Levelero]

Boucheron, Chanel, Chaumet, Chopard, Dinh Van or Vhernier.

Between all them, i must buy some item/s, to have access to buy my wished timepiece.

I am looking for something iconic piece that could hold value rather good to present to my couple (never mind if earings, ring, bracelet, etc…)

Thanks in Advance.

Best,
M
