About this 1.74ct lab-grown oval diamond

This 1.74ct lab-grown oval sits in the one-and-a-half to two carat band, graded E colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG823657837 or 823657837. Listed at 7 retailers as of October 29, 2026, with prices from €290 to €1,173, a €882 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.
