About this 1.45ct lab-grown cushion diamond

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 IF clarity (flawless or internally-flawless) and certified by IGI LG780661400 or 780661400. Listed at 13 retailers as of October 30, 2026, with prices from $508 to $3,744, a $3,235 spread on the same certified stone. Do Amore Diamonds lists it at $3,744. 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.
