Diamonds II

In this blog, my second on diamonds, I’ll discuss the physical and chemical properties of a diamond, then its optical properties in relation to its crystal structure and chemistry, and then their formation and associated geology.   CRYSTAL STRUCTURE AND PROPERTIES OF DIAMOND To understand the physical properties of the diamond it’s important to understand its. . .
