This 1.89ct lab-grown round sits in the one-and-a-half to two carat band, graded F colour (colourless) and SI2 clarity (slightly-included), with a very-good cut grade and certified by IGI LG763668399 or 763668399. Listed at 14 retailers as of October 31, 2026, with prices from €208 to €1,173, a €965 spread on the same certified stone. Brilliant Earth lists it at €1,173. 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.
