This 1.18ct 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 LG784646692 or 784646692. Listed at 16 retailers as of October 30, 2026, with prices from £237 to £2,097, a £1,861 spread on the same certified stone. Do Amore Diamonds lists it at £2,097. 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.
