About this 4.55ct lab-grown cushion diamond

This 4.55ct lab-grown cushion sits in the three to five carat band, graded D colour (colourless) and FL clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG800677238 or 800677238. Listed at 9 retailers as of November 2, 2026, with prices from $4,606 to $29,360, a $24,754 spread on the same certified stone. Do Amore Diamonds lists it at $29,360. 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.
