About this 1.1ct lab-grown heart diamond

This 1.1ct lab-grown heart sits in the classic one-carat band, graded F colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG846690722 or 846690722. Listed at 5 retailers as of November 1, 2026, with prices from £236 to £638, a £402 spread on the same certified stone. MOH London lists it at £638. 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.
