This 1.2ct lab-grown heart sits in the classic one-carat band, graded D colour (colourless) and VS2 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG837660881 or 837660881. Listed at 7 retailers as of October 28, 2026, with prices from $195 to $1,019, a $824 spread on the same certified stone. MOH London lists it at $1,019. 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.
