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 2507498430. Listed at 16 retailers as of November 4, 2026, with prices from HK$17,485 to HK$34,837, a HK$17,352 spread on the same certified stone. MOH London lists it at HK$34,837. 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.
