About this 1ct natural cushion diamond

This 1ct natural cushion sits in the classic one-carat band, graded I 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 6375936754. Listed at 17 retailers as of November 6, 2026, with prices from HK$16,012 to HK$24,782, a HK$8,770 spread on the same certified stone. Washington Diamond lists it at HK$24,782. 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.
