Gold Hallmark on Masonic Ring

[offthewood]

I was hoping to date this ring by the hallmark. The photo is not that great for the hallmark and there is considerable wear. It looks like a triangle in a circle. Thanks in advance.

Apparently this is not a hallmark. I have received information that this is a symbol of the ROYAL ARCH MASONS and after a little research I believe this information to be correct. I can draw no conclusion as to why this mark is there unless they have their own craftsman.
