About this 0.62ct lab-grown round diamond

This 0.62ct lab-grown round sits in the half to three-quarter carat band, graded G colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG301781297 or 301781297. Listed at 2 retailers as of October 31, 2026, with prices from €238 to €367, a €129 spread on the same certified stone. Brilliant Earth lists it at €367. 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.
