About this 3.03ct lab-grown asscher diamond

This 3.03ct lab-grown asscher sits in the three to five carat band, graded F colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6462818077. Listed at 11 retailers as of November 4, 2026, with prices from £966 to £3,381, a £2,415 spread on the same certified stone. Brilliant Earth lists it at £3,381. 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.
