About this 1.37ct lab-grown cushion diamond

This 1.37ct 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 LG727563595 or 727563595. Listed at 9 retailers as of October 31, 2026, with prices from £460 to £1,598, a £1,137 spread on the same certified stone. Taylor and Hart lists it at £1,598. 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.
