About this 0.9ct natural cushion diamond

This 0.9ct natural cushion sits in the just-under-one-carat band, graded K colour (faint-tinted) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 1379395697. Listed at 9 retailers as of November 4, 2026, with prices from HK$10,361 to HK$22,266, a HK$11,905 spread on the same certified stone. MOH London lists it at HK$22,266. 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.
