This 3ct lab-grown heart sits in the three to five carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG828681340 or 828681340. Listed at 25 retailers as of October 30, 2026, with prices from $1,804 to $22,425, a $20,621 spread on the same certified stone. Novita Diamonds lists it at $22,425. 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.
