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 LG825667270 or 825667270. Listed at 19 retailers as of November 5, 2026, with prices from $553 to $2,393, a $1,840 spread on the same certified stone. MOH London lists it at $2,393. 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.
