This 3.18ct lab-grown asscher sits in the three to five carat band, graded G colour (near-colourless) and VS1 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG11372101 or 11372101. Listed at 10 retailers as of October 26, 2026, with prices from £421 to £2,242, a £1,821 spread on the same certified stone. MOH London lists it at £2,242. 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.
