This 0.53ct lab-grown heart sits in the half to three-quarter carat band, graded D colour (colourless) and FL clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG840620848 or 840620848. Listed at 5 retailers as of November 5, 2026, with prices from $300 to $1,328, a $1,028 spread on the same certified stone. MOH London lists it at $1,328. 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.
