About this 0.54ct lab-grown heart diamond

This 0.54ct lab-grown heart sits in the half to three-quarter carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG729533700 or 729533700. Listed at 18 retailers as of November 4, 2026, with prices from $385 to $2,088, a $1,703 spread on the same certified stone. Reve Diamonds lists it at $2,088. 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.
