A Garnesson tortoiseshell, silver and gold pique desk set?

[Juliopm]

Goodmorning,
I've this desk set with a paper label under the base "Garnesson palais Royal 155". I've found that Nicolas-Jacques Garnesson was a merchant of necessaires collaborating for the suppliers of the Imperial court and the Bourbon court. He died in 1824 anf his son Hippolyte took over the family bussiness.
There are some marks (the silversmiths and another one) in only two pieces, not very readable. I think the pique is a gold one, the colour is different from the other metal parts, that are of vermeil. I think that a leather cover is missing. Can anybody help me in understand its provenance? Thank you!

Regards,
Julio

Hippolyte Garnesson was one of several specialists in necessaires at Palais Royal, Paris. In 1827 he partnered with Achille CHOMPRET and they formed a new company on 15 February 1832 under the name Chompret & Company.

Thank you so much for this information! So, probably, the desk set was made before 1832...

Yes, certainly before 1832, and the style suggests this as well.
