About this 0.91ct lab-grown heart diamond

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 1, 2026, with prices from £289 to £1,254, a £965 spread on the same certified stone. MOH London lists it at £1,254. 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.
