About this 1.75ct lab-grown pear diamond

This 1.75ct lab-grown pear sits in the one-and-a-half to two carat band, graded E colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade and certified by IGI LG515212990 or 515212990. Listed at 10 retailers as of October 29, 2026, with prices from £309 to £1,247, a £937 spread on the same certified stone. Brilliant Earth lists it at £1,247. 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.
