This 1.26ct lab-grown round sits in the one-and-a-quarter to one-and-a-half carat band, graded E colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG766644661 or 766644661. Listed at 10 retailers as of November 2, 2026, with prices from $456 to $1,243, a $787 spread on the same certified stone. MOH London lists it at $1,243. 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.
