This 1.23ct lab-grown radiant sits in the classic one-carat band, graded D colour (colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG739585776 or 739585776. Listed at 15 retailers as of October 30, 2026, with prices from €150 to €1,450, a €1,300 spread on the same certified stone. Do Amore Diamonds lists it at €1,450. 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.
