This 1.21ct lab-grown heart sits in the classic one-carat band, graded F colour (colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG840639927 or 840639927. Listed at 13 retailers as of November 3, 2026, with prices from $327 to $1,591, a $1,263 spread on the same certified stone. Reve Diamonds lists it at $1,591. 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.
