This 1.34ct 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 LG722514138 or 722514138. Listed at 13 retailers as of October 29, 2026, with prices from $303 to $1,863, a $1,560 spread on the same certified stone. Brilliant Earth lists it at $1,863. 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.
