About this 0.4ct lab-grown round diamond

This 0.4ct lab-grown round sits in the sub-half-carat band, graded M colour (faint-tinted) and VVS2 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LGF6E19946 or F6E19946. Listed at a single retailer as of November 4, 2026. If it later appears at another store, Carat Hunter will surface the price comparison automatically. 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.
