About this 1.21ct lab-grown heart diamond

This 1.21ct 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 LG818653848 or 818653848. Listed at 12 retailers as of November 1, 2026, with prices from $221 to $1,900, a $1,679 spread on the same certified stone. Do Amore Diamonds lists it at $1,900. 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.
