This 1.5ct lab-grown round sits in the one-and-a-half to two carat band, graded H colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG436073051 or 436073051. Listed at 11 retailers as of November 5, 2026, with prices from €1,007 to €4,680, a €3,673 spread on the same certified stone. MOH London lists it at €4,680. 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.
