About this 2.6ct lab-grown cushion diamond

This 2.6ct lab-grown cushion sits in the two to three carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG845699657 or 845699657. Listed at 12 retailers as of October 24, 2026, with prices from £1,012 to £3,072, a £2,059 spread on the same certified stone. Taylor and Hart lists it at £3,072. 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.
