This 1.56ct lab-grown radiant sits in the one-and-a-half to two carat band, graded D colour (colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG689522824 or 689522824. Listed at 25 retailers as of October 30, 2026, with prices from $277 to $2,033, a $1,755 spread on the same certified stone. Brilliant Earth lists it at $2,033. 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.
