About this 3.09ct lab-grown cushion diamond

This 3.09ct lab-grown cushion sits in the three to five carat band, graded F colour (colourless) and IF clarity (flawless or internally-flawless), with a standard cut grade and certified by IGI LG633464388JKH or 633464388JKH. Listed at a single retailer as of November 1, 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.
