About this 1.02ct natural cushion diamond

This 1.02ct natural cushion sits in the classic one-carat band, graded J 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 1373934831. Listed at 18 retailers as of November 6, 2026, with prices from HK$15,698 to HK$24,225, a HK$8,527 spread on the same certified stone. Washington Diamond lists it at HK$24,225. 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.
