About this 0.5ct natural cushion diamond

This 0.5ct natural cushion sits in the half to three-quarter carat band, graded H colour (near-colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6521458289. Listed at 12 retailers as of November 2, 2026, with prices from HK$2,966 to HK$8,191, a HK$5,225 spread on the same certified stone. MOH London lists it at HK$8,191. 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.
