About this 0.41ct lab-grown round diamond

This 0.41ct lab-grown round sits in the sub-half-carat band, graded I colour (near-colourless) and SI2 clarity (slightly-included), with a very-good cut grade and certified by IGI LG459130449 or 459130449. Listed at 9 retailers as of October 29, 2026, with prices from $177 to $1,030, a $853 spread on the same certified stone. MOH London lists it at $1,030. 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.
