About this 0.4ct natural cushion diamond

This 0.4ct natural cushion sits in the sub-half-carat band, graded E colour (colourless) and SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 1515556923. Listed at 9 retailers as of October 29, 2026, with prices from $788 to $3,018, a $2,230 spread on the same certified stone. NZ Jewellers lists it at $3,018. 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.
