This 1.14ct lab-grown radiant sits in the classic one-carat band, graded F colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade and certified by IGI LG615343038 or 615343038. Listed at 11 retailers as of November 2, 2026, with prices from $145 to $1,400, a $1,255 spread on the same certified stone. Do Amore Diamonds lists it at $1,400. 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.
