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 FL clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG818658536 or 818658536. Listed at 18 retailers as of October 30, 2026, with prices from $483 to $2,648, a $2,165 spread on the same certified stone. Brilliant Earth lists it at $2,648. 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.
