Let's play a game... rainbow gems.

[Crimson]

The current color is orange. I'll justify cheating a little since it has been a couple weeks since the last post. Only part of the stone is orange.

5mm no oil red beryl with a particularly strong orange streak across the center.
Any takers for yellow?

Fabulous, I have always wanted a red beryl! Thank you @toomuch8 for getting this game going again! Inspired by you, I am going to use the yellow tinge on the right side of my creamy “mutton fat” nephrite pendant to keep things moving.

The Benitoite family! Do note that the largest cabochon in the last picture is a sapphire that got mixed in with that lot. Still blue though!
