By dividing an overall diamond weight equally between two or more diamonds within a ring, the overall diamond cost in any one particular colour and clarity will almost certainly work out more cost effective than a single stone. Additionally such multi-diamond combinations can be worked into a host of differing styles of veryunusual engagement rings. These are multi-purpose designs, we must stress, not particularly serving an exclusive function as an engagement ring, but this could form a ring purchased for occasional or every day wear, not just for the engagement ring itself.
