Diamond - Wikipedia

Diamond is a solid form of pure carbon with its atoms arranged in a crystal. Solid carbon comes in different forms known as allotropes depending on the type of chemical bond. The two most common allotropes of pure carbon are diamond and graphite.In graphite the bonds are sp 2 orbital hybrids and the atoms form in planes with each bound to three nearest neighbors 120 degrees apart.

Crystal detector - Wikipedia

Silicon detector. Patented and first manufactured in 1906 by Pickard, this was the first type of crystal detector to be commercially produced. Silicon required more pressure than the whisker contact, although not as much as carborundum. A flat piece of silicon was eedded in fusible alloy in a metal cup, and a metal point, usually brass or gold, was pressed against it with a spring.
