About this 0.55ct natural cushion diamond

This 0.55ct 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 6565550236. Listed at 2 retailers as of October 28, 2026, with prices from $435 to $539, a $104 spread on the same certified stone. 77 Diamonds lists it at $539. 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.
