About this 1.2ct lab-grown heart diamond

This 1.2ct lab-grown heart sits in the classic one-carat band, graded E colour (colourless) and VS2 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG843652519 or 843652519. Listed at 9 retailers as of October 30, 2026, with prices from $410 to $2,012, a $1,602 spread on the same certified stone. Reve Diamonds lists it at $2,012. 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.
