About this 0.5ct natural cushion diamond

This 0.5ct 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 3555537917. Listed at 14 retailers as of October 29, 2026, with prices from HK$3,625 to HK$9,128, a HK$5,503 spread on the same certified stone. MOH London lists it at HK$9,128. 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.
