About this 1.02ct lab-grown asscher diamond

This 1.02ct lab-grown asscher sits in the classic one-carat band, graded E colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade and certified by IGI LG754525780 or 754525780. Listed at 7 retailers as of October 27, 2026, with prices from $189 to $447, a $258 spread on the same certified stone. Diamond Heaven lists it at $447. 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.
