About this 1.1ct lab-grown cushion diamond

This 1.1ct lab-grown cushion 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 LG833637808 or 833637808. Listed at 15 retailers as of October 29, 2026, with prices from £321 to £2,448, a £2,127 spread on the same certified stone. Do Amore Diamonds lists it at £2,448. 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.
