About this 1.2ct natural round diamond

This 1.2ct natural round sits in the classic one-carat band, graded J colour (near-colourless) and SI2 clarity (slightly-included), with a very-good cut grade and certified by GIA 5413856974. Listed at 16 retailers as of November 5, 2026, with prices from HK$13,841 to HK$38,921, a HK$25,080 spread on the same certified stone. NZ Jewellers lists it at HK$38,921. 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.
