This 4.25ct lab-grown asscher sits in the three to five carat band, graded E colour (colourless) and VVS2 clarity (very-very-slightly-included), with a standard cut grade and certified by IGI LG604377165 or 604377165. Listed at 12 retailers as of October 29, 2026, with prices from £740 to £3,709, a £2,970 spread on the same certified stone. Brilliant Earth lists it at £3,709. 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.
