This 1.81ct lab-grown radiant sits in the one-and-a-half to two carat band, graded E colour (colourless) and VS2 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG589307189 or 589307189. Listed at 12 retailers as of October 28, 2026, with prices from $862 to $3,080, a $2,219 spread on the same certified stone. Brilliant Earth lists it at $3,080. 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.
