Have you eliminated ZnSe?: http://www.almazoptics.com/ZnSe.html

It doesn't match exactly but some of what you describe sounds similar
enough to ZnSe and not similar to most other materials.

I did consider it, thanks. I think my error bars on the index and density
are pretty generous and ZnSe falls outside this. Besides, the color is not
orange enough for ZnSe.

Of course, the ZnSe I am familiar with is made by CVD. Are there older
processes for growing CVD that might give significantly different density
(4.49 vs. 5.29) and color?
