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: http://www.gemologyonline.com/Forum/php ... php?t=3771 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. |
