Vintage blue zircon pin

I already posted this in the vintage jewelry section but I’m curious what the colored stone experts think.

Blue zircon vintage pin

Hi everyone. I am very excited to announce the arrival of my new vintage blue zircon pin. I think the white stones are white zircon but I’m not sure. It’s in really good condition and is heavy 18k gold (unmarked but tested). I wish jewelers were open so I can verify all of that but I’m going to...

Centre stone looks like it could easily be a treated Blue Zircon to me.

The stone looks to be in excellent condition. How large (mm) is it? Can't tell if they are zircon from your pictures. Would be great if you can play around with the piece to see whether you can pick up any doubling. My zircon exhibits this very strongly.

Gorgeous. Not an expert but I love the center stone and hope it turns out to be a zircon for you.

It's very pretty whatever it turns out to be!

I thought most blue zircons were treated to make them blue (start off brown)? I do see some doubling or "blurriness" to the stone. It's pretty big - around 7mm I think.
