About this 1.81ct lab-grown asscher diamond

This 1.81ct 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 LG766657032 or 766657032. Listed at 21 retailers as of November 1, 2026, with prices from £180 to £906, a £727 spread on the same certified stone. Brilliance lists it at £906. 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.
