This 1.65ct 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 LG778692265 or 778692265. Listed at 16 retailers as of October 28, 2026, with prices from €226 to €1,235, a €1,010 spread on the same certified stone. Brilliant Earth lists it at €1,235. 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.
