This 0.81ct lab-grown heart sits in the just-under-one-carat band, graded E colour (colourless) and FL clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG836618820 or 836618820. Listed at 17 retailers as of October 30, 2026, with prices from $457 to $2,251, a $1,794 spread on the same certified stone. Reve Diamonds lists it at $2,251. 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.
