About this 0.57ct lab-grown cushion diamond

This 0.57ct lab-grown cushion sits in the half to three-quarter carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG764675189 or 764675189. Listed at 9 retailers as of October 30, 2026, with prices from £228 to £1,679, a £1,451 spread on the same certified stone. Do Amore Diamonds lists it at £1,679. 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.
