About this 1.43ct lab-grown heart diamond

This 1.43ct lab-grown heart sits in the one-and-a-quarter to one-and-a-half carat band, graded E colour (colourless) and FL clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG831698102 or 831698102. Listed at 12 retailers as of October 28, 2026, with prices from $647 to $4,521, a $3,874 spread on the same certified stone. Brilliant Earth lists it at $4,521. 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.
