This 1.21ct lab-grown heart sits in the classic one-carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG836619501 or 836619501. Listed at 20 retailers as of November 2, 2026, with prices from $345 to $2,781, a $2,436 spread on the same certified stone. Brilliant Earth lists it at $2,781. 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.
