This 1.55ct lab-grown radiant sits in the one-and-a-half to two carat band, graded E colour (colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG706530148 or 706530148. Listed at 25 retailers as of October 23, 2026, with prices from $351 to $2,512, a $2,161 spread on the same certified stone. Brilliant Earth lists it at $2,512. 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.
