What Is the Mineral Beryl Used For? | Sciencing
Scientific Uses of Beryl. Beryl contains a very rare element called beryllium, which is only found in about 100 minerals. That makes it very significant to the scientific community, although they have also used beryl in a few other applications. One of the most common is the production of wire, although beryl has also been used on space shuttles.

Hehe, thanks. I'm familiar with the chemical difference, but I was thinking it might be a bit like lead or mercury (that is, a variety of compounds being similarly toxic to the native metal when ingested), and I did read some reports of chronic beryllium poisoning in beryllium mines (where I assume the major ore would be beryl).
