About this 0.4ct lab-grown cushion diamond

This 0.4ct lab-grown cushion sits in the sub-half-carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG799697349 or 799697349. Listed at 16 retailers as of November 2, 2026, with prices from $311 to $1,521, a $1,210 spread on the same certified stone. MOH London lists it at $1,521. 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.
