About this 1.28ct lab-grown asscher diamond

This 1.28ct lab-grown asscher sits in the one-and-a-quarter to one-and-a-half carat band, graded E colour (colourless) and VVS1 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG831690415 or 831690415. Listed at 15 retailers as of October 29, 2026, with prices from £139 to £888, a £749 spread on the same certified stone. Brilliant Earth lists it at £888. 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.
