About this 0.7ct natural cushion diamond

This 0.7ct natural cushion sits in the half to three-quarter carat band, graded F colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 6435923603. Listed at 11 retailers as of October 31, 2026, with prices from $2,596 to $4,769, a $2,173 spread on the same certified stone. Cape Diamonds lists it at $4,769. 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.
