Congrats & welcome.
Probably opal, & that 5 & 3.....
could that be 585....
Besides my jewelers loop my jeweler gave me,
the best magnifier I got, the husband pulled out of a Cracker Jack box,
as his "prize", lol.

I immediately confiscated it....

the man had no idea what he had...

I put it up to the camera lens when taking pics, it produces great magnified pics,
if you have magnifiers around there, play with different ones & your camera,
you may could get lucky & have one that "will do", for a while.
