About this 1ct lab-grown heart diamond

This 1ct lab-grown heart sits in the classic one-carat band, graded F colour (colourless) and VS2 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG837683448 or 837683448. Listed at 8 retailers as of November 2, 2026, with prices from £241 to £737, a £495 spread on the same certified stone. MOH London lists it at £737. 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.
