Lovely blue stone, fluoresces red

[avidcollector]

Sometimes it appears darker than this photo. Depends on the lighting. I want to call it a sapphire ? It fluoresces red, but not as strong as rubies I own. I've had other sapphires that are inert under uv. I have read that natural sapphires fluoresce red. The surrounding white stones aren't diamonds, but register quite strongly on the tester, stopping just short of making it beep. It's a difficult stone to see through with the equipment I've got, quite dark once you get to the depths.

Opinions please? The colour is so beautiful I'm thinking it has to be heat treated or dyed.

Set in 9ct gold, with no hallmarks other than 9ct.

Thank you






call it

I will give you my opinion and a piece of advice.

My opinion is that it’s a synthetic sapphire. Color is too perfect and even, no visible inclusions + very low quality side stones

My advice is that you ignore my opinion and send it to the lab of your choice for their cheapest report to identify the stone.

Thank you. Your reply made me smile. It is very blue - suspiciously so.
It's late night here atm, and my eyes are failing but tomorrow I'll see if I can get a better look under magnification. I just remembered I have a usb magnifier somewhere that I never get out, so might use it to look for inclusions.

Not totally related to the center stone but those side stones look super brown, but possibly dirty. Has this thing been properly cleaned?

This stone is what I would consider as too good to be true, and my advice would be to treat with caution.

Depending on the price of the piece, if it is costume jewellery price no more than 200 USD, then it is probably worth taking the risk to buy it then send to a lab for testing, in the hope that it is a genuine Sapphire.

However, if the seller is asking for a lot more, then I would expect for the stone to come with a certificate from a reputable lab.

Hi Caolsen - They are clear gemstones to the naked eye. I have only just received the ring and it had a layer of grime, particularly on the back. I soaked it for a bit and did a bit of a clean, but I need to do it again, more thoroughly. I bought it online and it actually came to me in a thin cardboard envelope with no padding at all. The setting had poked a hole through the cardboard. So I initially I was just relieved it appeared to be in one piece with no damage.
Now you've mentioned it, I guess the grime might mess with the diamond tester, so maybe I should test them again after a good clean.

Thanks DK - too late for that haha. I bought it online, with the seller making no claims as to what the stone was, other than blue. I was expecting it to be paste, but it tests strongly as a gemstone and also fluoresces red.
She said it belonged to her aunt and she was selling other stuff (not jewellery) that would fit with deceased estate goods.

May I be nosy and ask how much you spent on this ring?

 

[avidcollector]

Sure - about $50AU.

Sure - about $50AU.

At that price it can only be synthetic or glass, no doubt
