About this 4.08ct lab-grown cushion diamond

This 4.08ct lab-grown cushion sits in the three to five carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG754563827 or 754563827. Listed at 23 retailers as of October 30, 2026, with prices from $3,063 to $19,700, a $16,637 spread on the same certified stone. Do Amore Diamonds lists it at $19,700. 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.
