This 1.45ct 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 standard cut grade and certified by IGI LG800677337 or 800677337. Listed at 10 retailers as of November 3, 2026, with prices from $534 to $3,710, a $3,176 spread on the same certified stone. Do Amore Diamonds lists it at $3,710. 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.
