About this 1.09ct lab-grown pear diamond

This 1.09ct lab-grown pear sits in the classic one-carat band, graded J colour (near-colourless) and SI1 clarity (slightly-included), with a standard cut grade and certified by IGI LG407948725 or 407948725. Listed at 11 retailers as of November 3, 2026, with prices from £463 to £2,887, a £2,424 spread on the same certified stone. MOH London lists it at £2,887. 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.
