About this 1.23ct lab-grown cushion diamond

This 1.23ct lab-grown cushion sits in the classic one-carat band, graded E colour (colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG646487003 or 646487003. Listed at 15 retailers as of October 30, 2026, with prices from €184 to €1,025, a €840 spread on the same certified stone. Reve Diamonds lists it at €1,025. 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.
