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 12 retailers as of October 26, 2026, with prices from $163 to $1,074, a $911 spread on the same certified stone. Reve Diamonds lists it at $1,074. 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.
