About this 1.13ct lab-grown heart diamond

This 1.13ct lab-grown heart sits in the classic one-carat band, graded F colour (colourless) and VVS1 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG743581979 or 743581979. Listed at 8 retailers as of November 6, 2026, with prices from £270 to £804, a £533 spread on the same certified stone. Michael Trio lists it at £804. 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.
