This 1.51ct lab-grown round sits in the one-and-a-half to two carat band, graded I colour (near-colourless) and VS2 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG555273605 or 555273605. Listed at 14 retailers as of October 25, 2026, with prices from €331 to €1,606, a €1,275 spread on the same certified stone. MOH London lists it at €1,606. 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.
