Is there a way to tell the difference between the two please? I suspect they both react the same way with a Chelsea Filter as both are from the Beryl family?

Thank you in advance.

Hi.
We've had a similar discussion before:

Are your gems rough or fashioned?

Thank you for the link - very interesting.

All are cut not rough. I know the RI should be different but I was just wondering if they react differently with a Chelsea Filter and I can't seem to find any information that tells me.

I personally would rely on Refractive Index for a separation.
