This 1.26ct lab-grown princess sits in the one-and-a-quarter to one-and-a-half carat band, graded D colour (colourless) and FL clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG784646488 or 784646488. Listed at 7 retailers as of October 29, 2026, with prices from $573 to $3,170, a $2,597 spread on the same certified stone. Brilliant Earth lists it at $3,170. 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.
