This 1.2ct lab-grown heart sits in the classic one-carat band, graded F colour (colourless) and VVS2 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG841662741 or 841662741. Listed at 5 retailers as of November 1, 2026, with prices from $434 to $1,521, a $1,087 spread on the same certified stone. MOH London lists it at $1,521. 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.
