About this 1.4ct natural cushion diamond

This 1.4ct natural cushion sits in the one-and-a-quarter to one-and-a-half carat band, graded E colour (colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6542932581. Listed at 8 retailers as of October 30, 2026, with prices from $3,600 to $5,217, a $1,617 spread on the same certified stone. GemTrove lists it at $5,217. 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.
