This 1.03ct lab-grown princess sits in the classic one-carat band, graded D colour (colourless) and FL clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG823695111 or 823695111. Listed at 19 retailers as of October 30, 2026, with prices from £312 to £1,955, a £1,643 spread on the same certified stone. Brilliant Earth lists it at £1,955. 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.
