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 VVS1 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG831680032 or 831680032. Listed at 8 retailers as of October 29, 2026, with prices from $377 to $2,221, a $1,844 spread on the same certified stone. Brilliant Earth lists it at $2,221. 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.
