About this 1.04ct lab-grown heart diamond

This 1.04ct 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 LG840620876 or 840620876. Listed at 19 retailers as of October 30, 2026, with prices from $688 to $3,691, a $3,002 spread on the same certified stone. Brilliant Earth lists it at $3,691. 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.
