About this 1.7ct lab-grown pear diamond

This 1.7ct lab-grown pear sits in the one-and-a-half to two carat band, graded F colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade and certified by IGI LG512222547 or 512222547. Listed at 14 retailers as of November 1, 2026, with prices from £156 to £775, a £619 spread on the same certified stone. MOH London lists it at £775. 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.
