What is it?
A very light, very stiff metal that is transparent to X-rays and dangerous to breathe as dust.
Why does it matter?
Beryllium is stiffer than steel at a quarter the weight, which is why it is in satellite optics, missile guidance and the James Webb telescope's mirrors.

Where it comes from in the rock
All ore minerals →These are the minerals that actually carry beryllium. A deposit is only an orebody if one of them is concentrated enough to pay for digging it up.

Bertrandite
A low-grade beryllium silicate in volcanic tuff, and the source of most Western beryllium production.

Beryl
The classic beryllium mineral. Most commercial beryllium now comes from bertrandite, a lower-grade but far more…

“Withheld” means the USGS suppressed the figure to avoid disclosing an individual company's data — it does not mean zero. Country rows do not always sum to the world total because the source rounds each figure independently and does not always break out an “other countries” line.
