This 1.36ct lab-grown cushion 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 LG784646647 or 784646647. Listed at 11 retailers as of November 3, 2026, with prices from £346 to £2,496, a £2,151 spread on the same certified stone. Do Amore Diamonds lists it at £2,496. 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.
