About this 1.01ct lab-grown heart diamond

This 1.01ct lab-grown heart sits in the classic one-carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG840620878 or 840620878. Listed at 16 retailers as of October 30, 2026, with prices from $284 to $1,854, a $1,570 spread on the same certified stone. Brilliant Earth lists it at $1,854. 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.
