About this 0.53ct natural cushion diamond

This 0.53ct natural cushion sits in the half to three-quarter carat band, graded D colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 2558261021. Listed at 3 retailers as of November 6, 2026, with prices from HK$3,464 to HK$4,434, a HK$970 spread on the same certified stone. 77 Diamonds lists it at HK$4,434. 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.
