Diamonds
Diamonds made through chemical vapor deposition typically contain hydrogen. AP has a story about "large" diamonds grown through CVD.
from AP:
Using a process called chemical vapor deposition (CVD), several groups have figured out how to make diamonds. But growing them over 3 carats has proved challenging.
"Our fabrication of 10-carat, half-inch, CVD diamonds is a major breakthrough," said Russell Hemley of the Carnegie Institution's Geophysical Laboratory.
The size is about five times what commercial diamond manufacturers can make using standard processes, Hemley and his colleagues said May 16, 2005.
