This 0.78ct lab-grown heart sits in the just-under-one-carat band, graded E colour (colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG833607070 or 833607070. Listed at 8 retailers as of October 29, 2026, with prices from £190 to £660, a £469 spread on the same certified stone. MOH London lists it at £660. 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.
