About this 1.31ct lab-grown cushion diamond

This 1.31ct 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 LG615373311 or 615373311. Listed at 6 retailers as of October 26, 2026, with prices from €471 to €1,355, a €885 spread on the same certified stone. Do Amore Diamonds lists it at €1,355. 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.
