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 3 retailers as of November 7, 2026, with prices from HK$4,177 to HK$4,867, a HK$690 spread on the same certified stone. Steven Stone lists it at HK$4,867. 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.
