About this 1.43ct lab-grown heart diamond

This 1.43ct lab-grown heart sits in the one-and-a-quarter to one-and-a-half carat band, graded E colour (colourless) and VVS1 clarity (very-very-slightly-included) and certified by IGI LGG1201808 or G1201808. Listed at 2 retailers as of October 28, 2026, with prices from £456 to £1,070, a £614 spread on the same certified stone. MOH London lists it at £1,070. 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.
