About this 1.34ct lab-grown cushion diamond

This 1.34ct lab-grown cushion sits in the one-and-a-quarter to one-and-a-half carat band, graded E colour (colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG823617188 or 823617188. Listed at 4 retailers as of October 28, 2026, with prices from £579 to £803, a £225 spread on the same certified stone. Zales lists it at £803. 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.
