About this 1.01ct lab-grown asscher diamond

This 1.01ct lab-grown asscher sits in the classic one-carat band, graded E colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG849626335 or 849626335. Listed at 7 retailers as of October 30, 2026, with prices from £125 to £471, a £346 spread on the same certified stone. Taylor and Hart lists it at £471. 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.
