About this 0.4ct lab-grown round diamond

This 0.4ct lab-grown round sits in the sub-half-carat band, graded J colour (near-colourless) and VVS2 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LGF6E19911 or F6E19911. Listed at 2 retailers as of October 28, 2026, with prices from $472 to $834, a $363 spread on the same certified stone. 18carati lists it at $834. 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.
