About this 3ct lab-grown heart diamond

This 3ct lab-grown heart sits in the three to five carat band, graded D colour (colourless) and FL clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG836621953 or 836621953. Listed at 20 retailers as of October 30, 2026, with prices from $3,970 to $23,620, a $19,650 spread on the same certified stone. Brilliant Earth lists it at $23,620. 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.
