This 2.5ct lab-grown cushion sits in the two to three carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a standard cut grade and certified by IGI LG745507847 or 745507847. Listed at 9 retailers as of October 27, 2026, with prices from £935 to £6,172, a £5,237 spread on the same certified stone. Do Amore Diamonds lists it at £6,172. 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.
