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 LG848639582 or 848639582. Listed at 7 retailers as of November 4, 2026, with prices from £238 to £672, a £433 spread on the same certified stone. MOH London lists it at £672. 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.
