Hi Silverfan, thank you for your trust.
In fact, the 925 mark within that distinctive oval suggests Italian silver made after 1970.
However, it should be noted that the important mark in Italian hallmarking is the official mark of the silversmith, whether author or retailer, who must have these characteristics.

The 800 or 925 punches within an oval are freely available, and anyone can buy them for a few euros and punch anything.
