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 LG825657604 or 825657604. Listed at 8 retailers as of October 30, 2026, with prices from $405 to $3,886, a $3,481 spread on the same certified stone. Do Amore Diamonds lists it at $3,886. 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.
