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 LG825667195 or 825667195. Listed at 21 retailers as of October 30, 2026, with prices from $371 to $2,740, a $2,369 spread on the same certified stone. Brilliant Earth lists it at $2,740. 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.
