About this 0.52ct lab-grown cushion diamond

This 0.52ct lab-grown cushion sits in the half to three-quarter carat band, graded D colour (colourless) and FL clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG830622694 or 830622694. Listed at 11 retailers as of November 1, 2026, with prices from £219 to £1,041, a £821 spread on the same certified stone. Reve Diamonds lists it at £1,041. 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.
