About this 1.01ct lab-grown round diamond

This 1.01ct lab-grown round sits in the classic one-carat band, graded F colour (colourless) and SI2 clarity (slightly-included), with a standard cut grade and certified by IGI LG447073965 or 447073965. Listed at 2 retailers as of November 1, 2026, with prices from $405 to $942, a $537 spread on the same certified stone. Brilliant Earth lists it at $942. 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.
