This 1.51ct lab-grown pear sits in the one-and-a-half to two carat band, graded D colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG839647789 or 839647789. Listed at 10 retailers as of October 26, 2026, with prices from £201 to £852, a £651 spread on the same certified stone. MOH London lists it at £852. 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.
