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 D colour (colourless) and FL clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG784646694 or 784646694. Listed at 11 retailers as of October 31, 2026, with prices from £476 to £3,000, a £2,524 spread on the same certified stone. Do Amore Diamonds lists it at £3,000. 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.
