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 SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG763605130 or 763605130. Listed at 12 retailers as of November 1, 2026, with prices from $180 to $1,041, a $861 spread on the same certified stone. MOH London lists it at $1,041. 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.
