About this 1.05ct lab-grown cushion diamond

This 1.05ct lab-grown cushion sits in the classic one-carat band, graded F colour (colourless) and VS2 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG817617855 or 817617855. Listed at 10 retailers as of October 30, 2026, with prices from $280 to $1,063, a $783 spread on the same certified stone. MOH London lists it at $1,063. 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.
