This 1.5ct 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 LG694575991 or 694575991. Listed at 24 retailers as of November 4, 2026, with prices from $298 to $2,024, a $1,726 spread on the same certified stone. Brilliant Earth lists it at $2,024. 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.
