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 LG836612942 or 836612942. Listed at 19 retailers as of October 30, 2026, with prices from $569 to $3,674, a $3,105 spread on the same certified stone. Brilliant Earth lists it at $3,674. 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.
