This 2.71ct lab-grown cushion sits in the two to three carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG739588289 or 739588289. Listed at 18 retailers as of October 29, 2026, with prices from £1,451 to £7,329, a £5,878 spread on the same certified stone. Brilliant Earth lists it at £7,329. 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.
