About this 3.1ct lab-grown heart diamond

This 3.1ct lab-grown heart sits in the three to five carat band, graded D colour (colourless) and FL clarity (flawless or internally-flawless), with a standard cut grade and certified by IGI LG784646272 or 784646272. Listed at 13 retailers as of October 30, 2026, with prices from $2,871 to $20,297, a $17,426 spread on the same certified stone. Do Amore Diamonds lists it at $20,297. 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.
