About this 0.4ct lab-grown round diamond

This 0.4ct lab-grown round sits in the sub-half-carat band, graded K colour (faint-tinted) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LGF5E81342 or F5E81342. Listed at 3 retailers as of November 4, 2026, with prices from $430 to $778, a $347 spread on the same certified stone. 18carati lists it at $778. 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.
