About this 0.5ct natural cushion diamond

This 0.5ct natural cushion sits in the half to three-quarter carat band, graded I colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 5526522877. Listed at 10 retailers as of November 2, 2026, with prices from HK$3,036 to HK$8,380, a HK$5,344 spread on the same certified stone. MOH London lists it at HK$8,380. 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.
