About this 1.59ct lab-grown round diamond

This 1.59ct 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 standard cut grade and certified by IGI LG720547065 or 720547065. Listed at 14 retailers as of October 31, 2026, with prices from €208 to €1,190, a €983 spread on the same certified stone. Brilliant Earth lists it at €1,190. 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.
