About this 1.31ct lab-grown princess diamond

This 1.31ct lab-grown princess sits in the one-and-a-quarter to one-and-a-half carat band, graded F colour (colourless) and FL clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG786646412 or 786646412. Listed at 12 retailers as of November 4, 2026, with prices from $445 to $3,944, a $3,499 spread on the same certified stone. Do Amore Diamonds lists it at $3,944. 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.
