About this 0.54ct lab-grown heart diamond

This 0.54ct lab-grown heart sits in the half to three-quarter carat band, graded E colour (colourless) and FL clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG825666402 or 825666402. Listed at 16 retailers as of October 30, 2026, with prices from $370 to $1,851, a $1,481 spread on the same certified stone. Reve Diamonds lists it at $1,851. 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.
