About this 0.79ct lab-grown heart diamond

This 0.79ct lab-grown heart sits in the just-under-one-carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG778616829 or 778616829. Listed at 14 retailers as of November 4, 2026, with prices from £503 to £2,522, a £2,019 spread on the same certified stone. MOH London lists it at £2,522. 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.
