“Shine Bright Like a Diamond” the Effect of Diamond Proportions on Brightness and Sparkle Factor

This 1.668 carat, J-color, VS-1 clarity, puppy from the Brian Gavin Blue collection certainly knows how to Shine Bright Like a Diamond! And since I had it sitting here on my desk, I thought that we could use it to discuss the effect of diamond proportions upon brightness and sparkle factor. I snapped this picture with my camera phone, so don’t expect too much from it, it’s only intended to demonstrate that this diamond is keeping me company this morning… and trust me, like most Leo’s it has a sparkling personality! By the way, you get extra points if you figure out the astrological reference as it applies to this brilliant puppy! Click here to read more.
