Here's a great stone- for a particular buyer. It's got an amazing cut. The 1.51:1 ratio is as long as you can without being too long.
The stone has an even brilliance. No bow tie.
The color is very close to Vivid Yellow.
So the issue here is the carbon crystal in the table,
If you have sharp eyes you will be able to pick it out.
So the stone works for someone not bothered by such a crystal - or maybe for use where the color brilliance and size will matter most... maybe a pendant.
Of course, the price reflects the clarity grade... so it's a bargain for the right buyer.
