This 1.72ct lab-grown heart sits in the one-and-a-half to two carat band, graded D colour (colourless) and FL clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG818653729 or 818653729. Listed at 10 retailers as of October 30, 2026, with prices from $1,180 to $10,486, a $9,306 spread on the same certified stone. Do Amore Diamonds lists it at $10,486. 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.
