This 1.55ct lab-grown radiant sits in the one-and-a-half to two carat band, graded F colour (colourless) and VVS1 clarity (very-very-slightly-included) and certified by IGI LG756574991 or 756574991. Listed at 6 retailers as of November 4, 2026, with prices from $531 to $3,254, a $2,723 spread on the same certified stone. Brilliant Earth lists it at $3,254. 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.
