This 1.5ct lab-grown round sits in the one-and-a-half to two carat band, graded J colour (near-colourless) and SI2 clarity (slightly-included), with a very-good cut grade and certified by IGI LG451056227 or 451056227. Listed at 11 retailers as of November 3, 2026, with prices from €739 to €3,674, a €2,935 spread on the same certified stone. MOH London lists it at €3,674. 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.
