Diamond fracture and cleavage
WebMay 5, 2024 · Diamonds have 4 perfect cleavage planes, meaning they can split into 4 different places. Gemstones can receive one of the following grades for cleavage: It’s … WebDiamond and graphite provide examples of cleavage. Both are composed solely of a single element, carbon. But in diamond, each carbon atom is bonded to four others in a tetrahedral pattern with short covalent bonds. …
