About this 1.53ct lab-grown heart diamond

This 1.53ct 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 LG840617129 or 840617129. Listed at 13 retailers as of October 31, 2026, with prices from $1,196 to $6,150, a $4,954 spread on the same certified stone. Brilliant Earth lists it at $6,150. 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.
