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 1537384280. Listed at 3 retailers as of November 6, 2026, with prices from HK$2,978 to HK$4,469, a HK$1,491 spread on the same certified stone. Steven Stone lists it at HK$4,469. 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.
