This 1.21ct 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 LG849654484 or 849654484. Listed at 7 retailers as of October 29, 2026, with prices from $265 to $1,134, a $870 spread on the same certified stone. Taylor and Hart lists it at $1,134. 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.
