Very old bowls need help :)

Happy Mothers Day!
These bowls are very old and I am having no luck finding something similar.
The words I may say wrong (concave)? on outer side of bowl with the gold inside.
It's not the needle etching but thicker. Era?
Thank you anything helpful.

 

6" diameter 2" high

 

Bumping "I hope"
Any ideas?

 

I think the indented pattern is molded into the glass and that this is called intaglio glass.
I did an image search for gold intaglio glass and got mostly goofus glass and reverse carved cameo glass, not much of anything like your bowls.

 

@LauraGarnet02 thanks for trying and reminder on Intaglio glass!
