Search for signet ring in Topics

My grandmother gave me a signet ring a week ago, and I was wondering if anyone could help me identify the coat of arms on the front of the ring. I don't know what metal it is made from, and there is no visible hallmark that I can see...

Found it stashed away in my grandpa's house after he passed, he was a polish immigrant, so it might be from there

I'm working on a simple little design for a present where I have this cheap gold plated signet ring and I'm going to be taking a small portion of those spiral shavings from a piece of brass stock and creating an Archimedean spiral pattern which needs to mate with the face of the ring. The inner metal of the ring is unknown, and due to the thinness of both materials welding seems out of the question. How should I mate these two objects together?

Anyone help me here..I have a wax master of a signet ring. If i use lost wax casting i will lose my original....This i do not want. Is there a mould making stuff that i can press the ring into leaving a negative to fill with silver.....
