About this 1.09ct lab-grown asscher diamond

This 1.09ct lab-grown asscher sits in the classic one-carat band, graded D colour (colourless) and VVS1 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG842604074 or 842604074. Listed at 22 retailers as of November 3, 2026, with prices from £129 to £858, a £729 spread on the same certified stone. Brilliant Earth lists it at £858. 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.
