About this 1.02ct natural cushion diamond

This 1.02ct natural cushion sits in the classic one-carat band, graded F colour (colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 1453769596. Listed at 15 retailers as of November 4, 2026, with prices from HK$19,202 to HK$30,221, a HK$11,019 spread on the same certified stone. Washington Diamond lists it at HK$30,221. 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.
