About this 1.04ct lab-grown round diamond

This 1.04ct lab-grown round sits in the classic one-carat band, graded F colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG846647421 or 846647421. Listed at 9 retailers as of October 26, 2026, with prices from $258 to $892, a $634 spread on the same certified stone. MOH London lists it at $892. 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.
