About this 1ct lab-grown asscher diamond

This 1ct lab-grown asscher sits in the classic one-carat band, graded F colour (colourless) and VS2 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG851679534 or 851679534. Listed at 6 retailers as of October 30, 2026, with prices from £209 to £525, a £316 spread on the same certified stone. Friendly Diamonds lists it at £525. 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.
