Found a ring yesterday. It looks like it's sterling silver. Marked "925" inside, also "RLM" and the other side of the ring is marked "Thailand."
My eBay coach/mentor says we can't list this until I have the size determined for certain. It seems to be about a 7, but I'm not absolutely certain yet. I ordered a "Mandrel Sizer Measuring Stick." I might just take it to a jeweler and have it measured so I can list it.
