About this 1ct lab-grown heart diamond

This 1ct lab-grown heart sits in the classic one-carat band, graded G colour (near-colourless) and VS2 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG457074012 or 457074012. Listed at 6 retailers as of November 1, 2026, with prices from £186 to £643, a £457 spread on the same certified stone. MOH London lists it at £643. 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.
