About this 0.9ct natural cushion diamond

This 0.9ct natural cushion sits in the just-under-one-carat band, graded E colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 1265037131. Listed at 22 retailers as of October 28, 2026, with prices from $2,497 to $6,443, a $3,946 spread on the same certified stone. Moon Ocean lists it at $6,443. 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.
