This 0.91ct lab-grown heart sits in the just-under-one-carat band, graded D colour (colourless) and FL clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG825667284 or 825667284. Listed at 18 retailers as of November 5, 2026, with prices from €344 to €1,490, a €1,146 spread on the same certified stone. MOH London lists it at €1,490. 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.
