About this 1.05ct natural cushion diamond

This 1.05ct natural cushion sits in the classic one-carat band, graded F colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6271986744. Listed at 21 retailers as of November 2, 2026, with prices from HK$26,991 to HK$56,041, a HK$29,050 spread on the same certified stone. MOH London lists it at HK$56,041. 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.
