Featured Help Identifying This Stone Please

Hello everyone
This little pendant was amongst my Gran's jewellery.
I have had a good look through the loupe and can't see any marks in the metal. There are also no bubbles in the stone.
Do you think glass or something else? Moonstone?
Thanks for looking.
Tracey

 

Charming little pendant, Tracey, very nice combination of the gold and the stone. It looks like blue chalcedony to me. The gold could be gold plated, difficult to tell.

Moonstone has a flash of colour that changes as you move the stone.

 

Thanks AJ. The stone definitely flashes and changes colour. It's difficult to photograph. Almost a little bit like an opal but not with the intense colour of an opal. Any thoughts regarding age?

 

Thanks Book hope all is well in your world. It's Australia Day today so a holiday for me

 

Lovely, in that case it could be a moonstone.

 

Oh, yes, so it is! Happy Australia Day!



Apologies to Tasmania and Melbourne, someone cut you off.

 

Thank you

 

Oops, I just noticed part of the north is cut off too.

 

You got the most important bit - WA

 

And NSW, where I used to live. (way back when....)

 

Is the stone translucent or opaque when held up to a light? I agree with most: Moonstone.

 

I would say opaque. A little bit milky.

 

@Any Jewelry or any of our other joolies any idea on age please.

 

With this internal orangy hue, I think it is not a stone, but opalite glass

Thinking 1970s for the era

 

Thank KT. Not as old as I first thought

 

It seems there is a bubble in your pic#1, at 9 o'clock...

 

You might be right. I've had another look through the loupe but can't work out if its a bubble or some dirt

 

The stone(?) of your pendent appears to have 2 tiny imperfections (unless they're caused by camera flash) which may suggest its made from a ceramic or a coloured paste perhaps? Opalite, Opalescent and also Opal glass will/should show some transparency and there will also be slight variants of colours subject to different light conditions.

 

Thank you for your comments. Is there some type of test I could do on the stone?
