This 1.33ct lab-grown round sits in the one-and-a-quarter to one-and-a-half carat band, graded F colour (colourless) and SI2 clarity (slightly-included), with a very-good cut grade and certified by IGI LG524238659 or 524238659. Listed at 8 retailers as of October 29, 2026, with prices from $165 to $1,064, a $899 spread on the same certified stone. MOH London lists it at $1,064. 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.
