About this 1.02ct lab-grown heart diamond

This 1.02ct 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 LG825655941 or 825655941. Listed at 19 retailers as of October 30, 2026, with prices from $607 to $3,318, a $2,711 spread on the same certified stone. Brilliant Earth lists it at $3,318. 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.
