About this 1ct natural cushion diamond

This 1ct natural cushion sits in the classic one-carat band, graded I colour (near-colourless) and SI2 clarity (slightly-included), with a very-good cut grade and certified by IGI 700529276. Listed at 12 retailers as of November 4, 2026, with prices from HK$12,023 to HK$32,188, a HK$20,166 spread on the same certified stone. NZ Jewellers lists it at HK$32,188. 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.
