Electron scanning reveals that fibrous and gem quality diamonds form from the same kinds of carbonate-containing fluids

(Phys.org)—A pair of researchers with The Hebrew University of Jerusalem has found evidence that suggests both gem quality and fibrous diamonds form from the same types of fluids. In their paper published in Earth and Planetary Science Letters, Brooke Matat Jablon and Oded Navon, describe their experiments with beams of electrons and multiple diamonds, both gem quality and fibrous, what they found and why they now believe all diamonds have a common source.
