About this 0.4ct lab-grown cushion diamond

This 0.4ct lab-grown cushion sits in the sub-half-carat band, graded E colour (colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by GCAL 302600017. Listed at a single retailer as of October 28, 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.
