About this 1.29ct lab-grown cushion diamond

This 1.29ct 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 standard cut grade and certified by IGI LG617442572 or 617442572. Listed at 9 retailers as of October 27, 2026, with prices from $192 to $1,560, a $1,368 spread on the same certified stone. Do Amore Diamonds lists it at $1,560. 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.
