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 very-good cut grade stated by the retailer rather than the lab and certified by GIA 6127251313. Listed at 4 retailers as of November 1, 2026, with prices from HK$25,516 to HK$52,553, a HK$27,038 spread on the same certified stone. MOH London lists it at HK$52,553. 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.
