About this 1.02ct lab-grown heart diamond

This 1.02ct lab-grown heart sits in the classic one-carat band, graded F colour (colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG840664707 or 840664707. Listed at 11 retailers as of November 4, 2026, with prices from £161 to £748, a £587 spread on the same certified stone. Brilliant Earth lists it at £748. 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.
