Remember, all diamonds are not created equal. Two diamonds of equal Carat Weight may vary substantially in price due to their Cut, Colour and Clarity. The carat weight of diamond rings is a very important determining factor in their value.
You wouldnt believe all the princess cut diamond that fall out of mountings while working in the yard or doing dishes.
When engagement rings is cut too deep light leaks out the bottom, brilliance is lost, and the gold engagement ring will appear to be dark.
