I inherited a ring. How can I tell what the stone is?

[PlaymobilPirate]

It was my grandmother's - she'll have got engaged 1940s I think but I've no idea whether it's as old as that or whether she replaced her original.

I think it's cubic or glass but it glowed blue under uv lights today when I got my nails done and heard that might mean it's real?

It's hugely sentimental so I'm only bothered in case I need to insure it. Would glass still be very shiny after all these years?

Take it to a jeweller and ask them. They should be able to tell.

I would but didn't want to feel silly if it's glass!

Why would you feel silly? Just say what you said in your op- you want to find out for insurance purposes but you’re fully prepared to be told it’s not “real”.

A decent jeweller will have dealt with far more awkward situations!

I did exactly that. I’d been told the ring was diamond and ruby but there was no way of telling. They jewellers were lovely and did a free guesstimate valuation (to check I didn’t need a real one for house insurance).

I almost hope it's glass as I'm wearing it every day. It's beautiful. To be honest though I'd be devastated if I lost it regardless of what it's made of.

Can I just nip into a high street jeweller?

There was a thread a while back where OP had taken her engagement ring back to the supposed jeweller toner it resized, and the poor man had to tell her very diplomatically it was a cubic zirconia rather than the diamond that OP’s fiancé had told her it was.

I always wonder if jewellers have to have a crash course in delivery bad news for cases like that!

Ouch Penny! At least I'd not be disappointed!

Ooh can we see a photo of it, OP?

Not the best pic

Go to a working jeweller, rather than a chain.

It's a lovely cut, whatever it is.

Can you update us when you find out?

The blue fluorescence is a very good indicator that it is a diamond.

Glass or zirconia would likely be rather scratched by now.

If it’s a diamond it will scratch glass but I can’t see if the settings would get in the way if you tried.

Any hallmarks on the band?

Very pretty btw.

That’s a really pretty ring

Ooh just seen the pic! It’s gorgeous

What a stunning ring OP!

The band has a gold hallmark.

The edging is slightly raised so don't think a scratch glass test would work. It makes me so happy (long story but she's been gone 6 years and we thought the rings were lost)

A ring she wore alongside it as an eternity ring turned out to be costume from M&S which is why I thought glass

Can you read the hallmark? If it says 750 it’s 18ct gold, if it says 375 it’s 9ct. Might give a bit more of a clue.

a nice high street jeweller will probably tell you, yes. They will just look through their loupe and know!

well cut glass often does look like that under UV lights.

whatever it turns out to be, enjoy your lovely ring!

I can't read the hallmark. Will get ds to try tomorrow, my eyesight isn't great!

I would be very surprised if that wasn't diamond with the setting and the cut of the stone, a beautiful ring OP (worked in a jewellers for many years)

Get the setting checked st the same time op, you don’t want to lose the stone whatever the value as it is important to you.
