About this 1.5ct lab-grown heart diamond

This 1.5ct lab-grown heart sits in the one-and-a-half to two carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG835685300 or 835685300. Listed at 21 retailers as of October 30, 2026, with prices from $423 to $3,503, a $3,080 spread on the same certified stone. Brilliant Earth lists it at $3,503. 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.
