This 1.05ct lab-grown marquise 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 LG831680175 or 831680175. Listed at 14 retailers as of October 31, 2026, with prices from €172 to €665, a €493 spread on the same certified stone. Friendly Diamonds lists it at €665. 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.
