About this 0.41ct lab-grown round diamond

This 0.41ct lab-grown round sits in the sub-half-carat band, graded J colour (near-colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LGF6F17937 or F6F17937. Listed at 2 retailers as of October 31, 2026, with prices from €414 to €695, a €281 spread on the same certified stone. 18carati lists it at €695. 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.
