About this 1.45ct lab-grown cushion diamond

This 1.45ct 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 LG733519309 or 733519309. Listed at 7 retailers as of October 29, 2026, with prices from £584 to £1,365, a £781 spread on the same certified stone. MOH London lists it at £1,365. 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.
