About this 1.24ct lab-grown heart diamond

This 1.24ct lab-grown heart sits in the classic one-carat band, graded E colour (colourless) and VVS1 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG843623946 or 843623946. Listed at 12 retailers as of November 1, 2026, with prices from $453 to $2,577, a $2,124 spread on the same certified stone. Brilliant Earth lists it at $2,577. 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.
