Is the density of a diamond consistent from one diamond to the next? The reason I ask is that I'm deciding between two diamonds: One's from Roger's Jewelers (same company as Kay and Osterman Jewelers) and one's from Blue Nile. One is .64k and the other is .55k but the .55 is actually a little bit bigger! So, could one diamond be denser than the other or is one company exaggerating/underestimating the weight of their diamond?
Thanks!
