About this 1ct natural cushion diamond

This 1ct natural cushion sits in the classic one-carat band, graded K colour (faint-tinted) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 2526130826. Listed at 9 retailers as of November 6, 2026, with prices from HK$6,254 to HK$9,516, a HK$3,262 spread on the same certified stone. GemTrove lists it at HK$9,516. 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.
