This 1.29ct 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 standard cut grade and certified by IGI LG760534226 or 760534226. Listed at 5 retailers as of November 2, 2026, with prices from $390 to $1,066, a $676 spread on the same certified stone. MOH London lists it at $1,066. 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.
