Diamond is number 10 on the Mohs scale, and is 40 times harder than Corundum, which is number 9 on the Moh's scale. It also has the most dense atom ical configuration of any mineral, and is transparent over the greatest number of wavelengths.ISTINGUISHING SIMILAR MINERALS. The only mineral that can possibly be be confused with Diamond is waterworn Quartz pebbles which may resemble waterworn Diamonds, but the hardness and luster of Diamond will easily differentiate the two.
.A disconformity is an unconformity between parallel layers of sedimentary rocks which represents a period of erosion or non-deposition.
Thanks for the A2A. An unconformity occurs when there is erosion of a layer or layers of deposited rock followed by the deposition of new sedimentary rock on top. It it called an unconformity because the ages of the layers of rock that are abutting each other are discontinuous at the unconformity.
