What Makes a Diamond Sparkle?

Diamonds are notoriously known for their sparkle and shine, but in the rough this is not the case. The crystallised carbon has to go through several processes in order for it to look like the finished product. Included in these processes is the cutting and polishing of the diamond, which are the main factors determining the sparkle and lustre of the diamond.

Diamond Cut

Being one of the four C’s the diamond cut is signalled as an important factor when choosing a diamond ordinarily. The cut is frequently classed as the most important characteristic of a diamond, and has the greatest influence on the diamonds beauty and appearance. Therefore, it is also the greatest determinate in the general sparkle of the stone.  The cut refers to the overall polish of the diamond from rough and is a measurement of the amount of light able to travel through the diamond. GIA rates the cut of diamonds on a scale from Excellent, Very Good, Good, Fair to Poor.
