This 0.77ct lab-grown asscher sits in the just-under-one-carat band, graded E colour (colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG851645639 or 851645639. Listed at 6 retailers as of October 30, 2026, with prices from £219 to £601, a £382 spread on the same certified stone. Taylor and Hart lists it at £601. 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.
