About this 0.9ct natural cushion diamond

This 0.9ct natural cushion sits in the just-under-one-carat band, graded F colour (colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6515690743. Listed at 12 retailers as of November 2, 2026, with prices from $2,000 to $5,611, a $3,611 spread on the same certified stone. Moon Ocean lists it at $5,611. 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.
