About this 1.03ct natural cushion diamond

This 1.03ct natural cushion sits in the classic one-carat band, graded J colour (near-colourless) and SI2 clarity (slightly-included), with a standard cut grade and certified by IGI 788644178. Listed at 9 retailers as of November 5, 2026, with prices from HK$9,209 to HK$24,100, a HK$14,891 spread on the same certified stone. NZ Jewellers lists it at HK$24,100. 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.
