Hi,
With an 1.76 réfractive index for a ruby, I am wondering what liquid solution of a similar index is used for analysis.
Does someone have the answer?
Thanks

Thank you Barbra. I have received and ‘played’ with dodimethane on rubies, and it works just fine. I am now looking forward at taking pictures of my rubies to share with group (see my other post)

Yes, it works like a charm.
Take care with it. If you get it on your hands wash it off.
It is very toxic.
