About this 1ct lab-grown asscher diamond

This 1ct lab-grown asscher sits in the classic one-carat band, graded F colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG687563099 or 687563099. Listed at 6 retailers as of November 1, 2026, with prices from £189 to £1,058, a £870 spread on the same certified stone. Do Amore Diamonds lists it at £1,058. 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.
