About this 5.39ct lab-grown cushion diamond

This 5.39ct lab-grown cushion sits in the over five carat band, graded D colour (colourless) and FL clarity (flawless or internally-flawless) and certified by IGI. Listed at a single retailer as of October 31, 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.
