Toughness of Diamond

Toughness relates to a material's ability to resist breakage from forceful impact. The toughness of natural diamond has been measured as 2.0 MPa·m1/2, and the critical stress intensity factor is 3.4 MN·m−3/2. Those values are good compared to other gemstones, but poor compared to most engineering materials. As with any material, the macroscopic geometry of a diamond contributes to its resistance to breakage. Diamond has a cleavage plane and is therefore more fragile in some orientations than others. Diamond cutters use this attribute to cleave some stones, prior to faceting.Diamond Toughness shows the Quality of the Diamonds.. Here Some Of the Beautiful Diamonds To Buy!!
