About this 1.01ct lab-grown heart diamond

This 1.01ct lab-grown heart sits in the classic one-carat band, graded F colour (colourless) and FL clarity (flawless or internally-flawless), with a standard cut grade and certified by IGI LG818657596 or 818657596. Listed at 19 retailers as of November 6, 2026, with prices from $532 to $2,527, a $1,995 spread on the same certified stone. Reve Diamonds lists it at $2,527. 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.
