Im sorry but if band is not marked its not ss and Id have to wonder if Diamonds are real For most Diamond real ones the band has a mark At least all mine do You can take it to a Jewelry Store to have Diamond tested I did and was not charged
......True....if it is SS or silver, it will say .925 inside the band
you have stated, intially, " Wife said around a 7.sterling silver with diamonds"
So IF these are NOT real diamonds and if this is NOT real sterling silver, you will need to delete this auction and start over....same thing on the other ring you have listed......If THEY ARE NOT REAL, as stated, sorry sir, you cannot follow thru
