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 LG673415577 or 673415577. Listed at 14 retailers as of October 31, 2026, with prices from £1,408 to £6,853, a £5,445 spread on the same certified stone. Adiamor lists it at £6,853. 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.
