About this 1.42ct lab-grown cushion diamond

This 1.42ct lab-grown cushion sits in the one-and-a-quarter to one-and-a-half carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG733519414 or 733519414. Listed at 7 retailers as of October 26, 2026, with prices from £573 to £1,353, a £779 spread on the same certified stone. MOH London lists it at £1,353. 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.
