help identifying mark on Dior silver

Hi. I need help identifying this mark I found on a Christian Dior decanter. I’m sorry for the poor quality photo. it appears to bring an R D with a cross in a circle. thanks for the assistance.

Looks like an anchor with R D next to it…

It can be the french silver plate mark for Ravinet D’Énfert from Paris founded in 1891. Look at: 925-1000.com/silverplate_R.html
