About this 1.15ct lab-grown radiant diamond

This 1.15ct lab-grown radiant sits in the classic one-carat band, graded I colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG634413023 or 634413023. Listed at 14 retailers as of November 1, 2026, with prices from €250 to €1,423, a €1,173 spread on the same certified stone. Do Amore Diamonds lists it at €1,423. 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.
