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 £238 to £2,110, a £1,872 spread on the same certified stone. Do Amore Diamonds lists it at £2,110. 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.
