About this 1.05ct lab-grown asscher diamond

This 1.05ct lab-grown asscher sits in the classic one-carat band, graded F colour (colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG836675625 or 836675625. Listed at 15 retailers as of November 4, 2026, with prices from £129 to £802, a £673 spread on the same certified stone. Brilliant Earth lists it at £802. 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.
