About this 1.5ct lab-grown asscher diamond

This 1.5ct lab-grown asscher sits in the one-and-a-half to two carat band, graded E colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG576355998 or 576355998. Listed at 2 retailers as of October 29, 2026, with prices from £544 to £645, a £101 spread on the same certified stone. Diamond Quarter lists it at £645. 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.
