Can anyone identify the stone in this ring

[Jjacobb]

I want to try and sell this ring on e bay. I don't know what the stone is though and wondered if anyone could help.
It's a very pale blue, not expensive (£100 about 15 years ago)

Topaz? No pic though?

Topaz, single A Tanzanite, Aquamarine, CZ, hard to telk without a pic.

Probably a dyed topaz

Duh, yes picture would help.

It looks more like aquamarine to me. Topaz is still pale but a deeper blue.

I second aquamarine, blue topaz is much deeper blue.

Could be an aquamarine or a coloured zircon.

Your best bet is to take it to an actual jewellers where it can be assessed properly.

Could be a topaz, could be an aquamarine, could be glass. Doesn't look like CZ to me. Obviously the most desirable would be the aquamarine but often the only way to tell the difference between a pale blue topaz and an aquamarine is through a jeweller's loop and sometimes pale blue topazes are wrongly (and often deliberately) sold as aquamarines for this reason. I once had an aquamarine and a pale topaz to show a client and it really was nigh on impossible to tell the difference (except for the price tag). If you really need to be certain I would take it to a gemologist as you wouldn't want to mis-sell.

have attempted to post pics of aquamarine and sky blue topaz below - very little to choose between them except the cost!

Could it be a tourmaline? They come in several colours, I had a very pale blue one like yours once

I'd say aquamarine. Blue topaz seems to be more turquoise-y to me than the ice blue that aquamarines are.
