If diamonds would sparkle more in claw settings, then i am sure that almost every diamond ring would be set that way. Understanding the way a diamond sparkles has more to do with the cut of a diamond than it does the setting that it is in. A diamond owes its sparkle to the precision of the diamond cutter. The way the diamond cutter expertly cuts and polishes every facet to be within the smallest of margins allows the light to bounce around inside the diamond and exit through the top of the stone.
The nemesis of a diamond cutter is light leakage. Having light leak out through the back or side of a diamond will lead to reduced diamond scintillation. It only takes one facet to be off one tenth of a degree for the light to escape out through the bottom of the stone. Likewise it only takes a small deviation on some of the top kite or star facets for you to get an unbalanced sparkle from the top of the diamond.
Have you ever looked at a diamond and thought that there was a dead spot in the stone where the diamond just looked dull ? It was most likely due to light being lost out through one side of the diamond. A perfectly cut diamond should sparkle evenly from one side of the diamond to the other.
Make sure that you don’t get a diamond with dead spots. The effect is magnified when the diamond becomes dirty. If you are wanting the maximum sparkle to come from your diamond ring then a high performance cut diamond like the Passion8 “Hearts and Arrows” Diamond is a great place to start.
The Passion8 diamond has a 99% light return rating. All Passion8 Diamonds have also been scored as a triple excellent for; Scintillation, Dispersion and Brilliance. Which means that it doesn’t matter what setting you put it into. It will sparkle just the same in a claw setting or a full bezel setting.

Not all triple excellent cut grade diamonds are equal.
