About this 1.5ct lab-grown asscher diamond

This 1.5ct 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 LG823639631 or 823639631. Listed at 19 retailers as of November 2, 2026, with prices from £248 to £1,244, a £996 spread on the same certified stone. Brilliant Earth lists it at £1,244. 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.
