About this 1ct natural radiant diamond

This 1ct natural radiant sits in the classic one-carat band, graded J colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 2557969510. Listed at 13 retailers as of November 3, 2026, with prices from HK$11,623 to HK$30,715, a HK$19,092 spread on the same certified stone. NZ Jewellers lists it at HK$30,715. 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.
