This 0.71ct lab-grown cushion sits in the half to three-quarter carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG660455014 or 660455014. Listed at 17 retailers as of November 3, 2026, with prices from £280 to £1,837, a £1,557 spread on the same certified stone. Do Amore Diamonds lists it at £1,837. 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.
