This 1.55ct lab-grown radiant sits in the one-and-a-half to two carat band, graded F colour (colourless) and VS1 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG687595692 or 687595692. Listed at 21 retailers as of November 4, 2026, with prices from $257 to $1,980, a $1,723 spread on the same certified stone. Brilliant Earth lists it at $1,980. 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.
