Jewellery: need advice on a 1960s sapphire ring

yellow hen

Hi, today I found a ring I loved in an antique shop in powers court. It was a large sapphire surrounded in .3 carat of diamonds in wht looked like a white gold frame. Two questions, as I felt the owner of the store was not very knowledgeable:

1. There was a small but visible scratch/mark on the sapphire. Is this possbke f t was a real sapphire.

2. The owner was unsure what the metal on the ring was. He was it was rhodium plated but was nature waht was underneath, but it was likely 18ct gold. When I asked if there was no sure way to find out, he said he'd have to file the ring.

The ring cost €725 and I loved it but would like people's advice. Thanks

If the ring itself is 18 ct gold then it should have a hallmark to certify that fact in which case it won't be plated with any other metal.

Without a hallmark there is no way in hell it's 18 ct gold and if the stone is real sapphire there is no way it can be scratched unless someone took another precious stone to it in anger. A sapphire is blue corundum, only diamond is harder so the stone you're looking at could not have been scratched unless it was attacked by a diamond or another corundum such as sapphire or ruby. No other metal or precious stone could have scratched it.

Doesn't add up, I'd walk away at a fast pace.
