This 0.7ct 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 LG840620870 or 840620870. Listed at 16 retailers as of November 4, 2026, with prices from $534 to $2,643, a $2,109 spread on the same certified stone. MOH London lists it at $2,643. 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.
