Does coal in a diamond lower the cost?


Recommended Posts

I have a 1/2k diamond and I recently went to the mall to help my sister look at engagement rings. While looking at rings I wanted to find out my ring clarity so the salesman put it under the microscope. To my surprise there is a lot of coal in the diamonds. I was just wondering if my fiance could have possibly over paid for my engagement ring. I never realized the coal spots before this time. I can even see the black spots with my naked eye is that normal?

Sometimes a diamodn has "imperfections"- sometimes the nature is black carbon spots.

This can dramatically lower the value of a diamond.

What did you pay?

It is black carbon spots you are right. I remember now that is what the salesman said at the jewelry store. I paid $600.
