About this 3.66ct lab-grown heart diamond

This 3.66ct lab-grown heart sits in the three to five carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 7511229099. Listed at 19 retailers, with prices from $3,685 to $27,630 at Kay Jewelers, a $23,945 spread on the same certified stone. Cut grade matters more than carat or clarity for visible brilliance. If you can shift budget toward an Excellent or Ideal cut, do it before chasing higher colour or clarity.
