About this 1ct natural cushion diamond

This 1ct natural cushion sits in the classic one-carat band, graded E 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 1418861366. Listed at 20 retailers as of October 29, 2026, with prices from HK$27,578 to HK$58,080, a HK$30,503 spread on the same certified stone. MOH London lists it at HK$58,080. 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.
