This 1.3ct 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 LG771638784 or 771638784. Listed at 5 retailers as of November 5, 2026, with prices from $589 to $1,573, a $984 spread on the same certified stone. MOH London lists it at $1,573. 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.
