About this 4.18ct lab-grown cushion diamond

This 4.18ct lab-grown cushion sits in the three to five carat band, graded D colour (colourless) and FL clarity (flawless or internally-flawless), with a standard cut grade and certified by IGI LG816625974 or 816625974. Listed at 9 retailers as of October 30, 2026, with prices from $5,174 to $32,280, a $27,106 spread on the same certified stone. Do Amore Diamonds lists it at $32,280. 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.
