This 10.56ct lab-grown heart sits in the over five carat band, graded E colour (colourless) and VVS2 clarity (very-very-slightly-included) and certified by IGI LG788666450 or 788666450. Listed at 22 retailers as of October 30, 2026, with prices from $2,418 to $14,400, a $11,982 spread on the same certified stone. Brilliant Earth lists it at $14,400. 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.
