Gift from Mother to Daughter

I'm really sad because my mother offered me the necklace several months ago and I lost it and my mother has died some days ago.

This is the last present I had from her and I would like to buy it again. I have gone to the shop where she bought it and they told me that it is out of stock.

I would like to know where I can buy this. I live in Paris. Thank you very much for your help, it is really important for me.
