This 1.5ct lab-grown round sits in the one-and-a-half to two carat band, graded J colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG480150373 or 480150373. Listed at 11 retailers as of November 3, 2026, with prices from €757 to €3,855, a €3,098 spread on the same certified stone. MOH London lists it at €3,855. 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.
