Question. Could the separation be made with a raman? |

Yes. Raman also readily separates the two. However Raman is probably even less available to the average gemologist... Best regards, Christopher P. Smith |

Ideal usecase for raman. Well, actually bytownite/scapolite more so, they overlap on almost every major indicator, and there was a rash of pale yellow bytownite being sold as scapolite rough a couple years back. |

Not everyone has one, but Everybody Loves Raman. |

Is it not a bit sad, when you don't have to search and make your mind work, and use your knowledge bit by bit, but only ask from a machine what this stone is ? |

Hi, what about color shift in amethyst vs scapolite ? |

75TURBO, I don't think color shift in amethyst (which I refer to as metamerism) would be definitive. Isi, as someone who uses my GemmoRaman daily, no I don't think it is sad. It is just another tool. Experience is necessary to interpret whether the results given by this tool are correct. Just like all our other tools. |

Only a minute for example to separate Taaffeite from Musgravite... But I agree that it is important to use your knowledge and the classic instruments - you learn so much more about gems. You need the basics and skills. |

I like being able to get more specific and detailed information more quickly. It's not like using a refractometer or sg scale is any more sophisticated or mentally stimulating, plus I don't like the smell of refractometer fluid. If I want fun and games with a stone (above and beyond what I get from the raman, which is decidedly fun and interesting) that is what my fleet of microscopes are for. |

It is about as sad as getting to fly over oceans instead of having to swim. Raman is a great technologically based tool. But it takes skill to use it to its fullest capabilities just like any other tool. I am never sad using it, I am always happy I have it. |
