This 0.78ct lab-grown heart sits in the just-under-one-carat band, graded D colour (colourless) and VVS1 clarity (very-very-slightly-included) and certified by IGI LG788666496 or 788666496. Listed at 8 retailers as of November 1, 2026, with prices from £269 to £849, a £580 spread on the same certified stone. MOH London lists it at £849. 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.
