About this 1.43ct lab-grown cushion diamond

This 1.43ct 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 standard cut grade and certified by IGI LG651420246 or 651420246. Listed at 16 retailers as of October 29, 2026, with prices from $401 to $2,058, a $1,657 spread on the same certified stone. Brilliant Earth lists it at $2,058. 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.
