About this 1.28ct lab-grown cushion diamond

This 1.28ct lab-grown cushion sits in the one-and-a-quarter to one-and-a-half carat band, graded D colour (colourless) and FL clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG800684844 or 800684844. Listed at 12 retailers as of November 4, 2026, with prices from $779 to $5,621, a $4,842 spread on the same certified stone. Do Amore Diamonds lists it at $5,621. 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.
