About this 0.53ct natural cushion diamond

This 0.53ct natural cushion sits in the half to three-quarter carat band, graded E colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6552786312. Listed at 2 retailers as of November 7, 2026, with prices from HK$4,389 to HK$5,086, a HK$697 spread on the same certified stone. Steven Stone lists it at HK$5,086. 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.
