This 1.33ct lab-grown radiant sits in the one-and-a-quarter to one-and-a-half carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG805623327 or 805623327. Listed at 23 retailers as of November 4, 2026, with prices from $381 to $4,614, a $4,233 spread on the same certified stone. Brilliant Earth lists it at $4,614. 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.
