About this 1ct lab-grown heart diamond

This 1ct lab-grown heart sits in the classic one-carat band, graded D colour (colourless) and FL clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG825632574 or 825632574. Listed at 19 retailers as of November 1, 2026, with prices from $501 to $3,172, a $2,670 spread on the same certified stone. Brilliant Earth lists it at $3,172. 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.
