About this 0.81ct lab-grown round diamond

This 0.81ct lab-grown round sits in the just-under-one-carat band, graded F colour (colourless) and VS1 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG677559837 or 677559837. Listed at 11 retailers as of October 26, 2026, with prices from £122 to £802, a £680 spread on the same certified stone. Reve Diamonds lists it at £802. 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.
