G. and Dr. Zhang, R. Y. from the Stanford University of USA have expressed their doubts about our discovery of micro-diamond, considering its weak intensity of Raman peak in our determination. Recently, we have determined the micro-diamond inclusion from the same sample 9010574 (fig. 1), tested展开更多
