About this 0.53ct natural cushion diamond

This 0.53ct natural cushion sits in the half to three-quarter carat band, graded F colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6521541724. Listed at 4 retailers as of November 1, 2026, with prices from $525 to $763, a $238 spread on the same certified stone. Ritani lists it at $763. 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.
