About this 0.78ct lab-grown asscher diamond

This 0.78ct lab-grown asscher sits in the just-under-one-carat band, graded D colour (colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG850695733 or 850695733. Listed at 6 retailers as of October 30, 2026, with prices from £212 to £495, a £284 spread on the same certified stone. Taylor and Hart lists it at £495. 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.
