This 1.55ct lab-grown radiant sits in the one-and-a-half to two carat band, graded E colour (colourless) and VVS2 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG640439806 or 640439806. Listed at 24 retailers as of October 26, 2026, with prices from $335 to $2,685, a $2,350 spread on the same certified stone. Brilliant Earth lists it at $2,685. 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.
