Material Properties<br />
3.1 General Properties<br />
<strong>Diamond</strong> is composed of carbon atoms arranged in the tetrahedron diamond lattice<br />
(g. 3.1). The atoms stick together through strong sp 3 -type bonds. The small carbon<br />
atoms give a very dense, but low weight lattice. These facts give reason <strong>for</strong> the<br />
extraordinary characteristics of diamond.<br />
