About this 1.54ct lab-grown heart diamond

This 1.54ct lab-grown heart sits in the one-and-a-half to two carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG825658597 or 825658597. Listed at 21 retailers as of October 28, 2026, with prices from $333 to $3,530, a $3,197 spread on the same certified stone. Brilliant Earth lists it at $3,530. 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.
