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 6371933957. Listed at 10 retailers as of November 6, 2026, with prices from HK$12,869 to HK$20,203, a HK$7,334 spread on the same certified stone. Yorxs lists it at HK$20,203. 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.
