About this 1.2ct natural cushion diamond

This 1.2ct 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 1557160054. Listed at 20 retailers as of November 2, 2026, with prices from HK$12,634 to HK$29,184, a HK$16,550 spread on the same certified stone. MOH London lists it at HK$29,184. 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.
