About this 1.34ct lab-grown heart diamond

This 1.34ct lab-grown heart sits in the one-and-a-quarter to one-and-a-half carat band, graded F colour (colourless) and VS2 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG593372620 or 593372620. Listed at 7 retailers as of November 2, 2026, with prices from £313 to £865, a £552 spread on the same certified stone. MOH London lists it at £865. 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.
