About this 1.36ct lab-grown cushion diamond

This 1.36ct lab-grown cushion sits in the one-and-a-quarter to one-and-a-half carat band, graded G colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG680547167 or 680547167. Listed at 3 retailers as of November 4, 2026, with prices from £548 to £1,018, a £470 spread on the same certified stone. Jared lists it at £1,018. 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.
