This 1.48ct 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 LG840623340 or 840623340. Listed at 4 retailers as of November 3, 2026, with prices from $1,394 to $4,102, a $2,708 spread on the same certified stone. Helzberg Diamonds lists it at $4,102. 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.
