About this 12.6ct lab-grown asscher diamond

This 12.6ct lab-grown asscher sits in the over five carat band, graded G colour (near-colourless) and VS1 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG702522409 or 702522409. Listed at 19 retailers as of October 30, 2026, with prices from £1,795 to £15,270, a £13,475 spread on the same certified stone. Brilliant Earth lists it at £15,270. 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.
