About this 1.23ct lab-grown cushion diamond

This 1.23ct lab-grown cushion sits in the classic one-carat band, graded G colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG615364001 or 615364001. Listed at 8 retailers as of October 27, 2026, with prices from €232 to €1,328, a €1,096 spread on the same certified stone. Do Amore Diamonds lists it at €1,328. 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.
