About this 1ct natural cushion diamond

This 1ct natural cushion sits in the classic one-carat band, graded I colour (near-colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6385370928. Listed at 21 retailers as of November 4, 2026, with prices from HK$13,794 to HK$30,199, a HK$16,405 spread on the same certified stone. MOH London lists it at HK$30,199. 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.
