Diamond Density

[fishter]

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!

the density is consistent. Parameters are not consistent

It's the cut. One diamond is cut with a larger "spread" than the other. This could be good or bad, depending on the mm sizes in question. The 0.64 might be a good depth, and the 0.55 "shallow", or the 0.55 a good depth, and the 0.64 "deep".

Do you have any of the cut specs on the diamonds? Diameter, etc.?

That's what Serg was saying also. I'm just translating his Russian shorthand.
