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 VS2 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG617452394 or 617452394. Listed at 5 retailers as of October 26, 2026, with prices from $910 to $1,470, a $560 spread on the same certified stone. Do Amore Diamonds lists it at $1,470. 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.
