About this 2.56ct lab-grown heart diamond

This 2.56ct lab-grown heart sits in the two to three carat band, graded F colour (colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG780691190 or 780691190. Listed at 6 retailers as of November 1, 2026, with prices from £534 to £1,303, a £770 spread on the same certified stone. MOH London lists it at £1,303. 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.
