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 standard cut grade and certified by IGI LG801686040 or 801686040. Listed at 16 retailers as of October 30, 2026, with prices from £325 to £2,888, a £2,563 spread on the same certified stone. Do Amore Diamonds lists it at £2,888. 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.
