These have evenly distributed microdiamonds that clearly show no indication of transport by magma.
Large-purity diamond wafers 5 cm in diameter exhibit perfect resistance in a single way and ideal conductance in another, producing the possibility of working with them for quantum info storage.
Diamonds are dated by examining inclusions utilizing the decay of radioactive isotopes. Based on the elemental abundances, one can think about the decay of rubidium to strontium, samarium to neodymium, uranium to steer, argon-forty to argon-39, or rhenium to osmium. People present in kimberlites have ages ranging from 1 to three.5 billion a long time, and there could be numerous ages in exactly the same kimberlite, indicating multiple episodes of diamond development.

As with every substance, the macroscopic geometry of a diamond contributes to its resistance to breakage. Diamond contains a cleavage plane and is also thus more fragile in some orientations than Other folks. Diamond cutters use this attribute to cleave some stones right before faceting them.[36] "Effect toughness" has become the main indexes to measure the caliber of synthetic industrial diamonds.
