About this 1.9ct lab-grown asscher diamond

This 1.9ct lab-grown asscher sits in the one-and-a-half to two carat band, graded F colour (colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG797650978 or 797650978. Listed at 3 retailers as of October 30, 2026, with prices from £661 to £873, a £213 spread on the same certified stone. The Diamond Guys lists it at £873. 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.
