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 E colour (colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG681512344 or 681512344. Listed at 15 retailers as of October 28, 2026, with prices from $244 to $1,560, a $1,316 spread on the same certified stone. Brilliant Earth lists it at $1,560. 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.
