About this 1.04ct natural radiant diamond

This 1.04ct natural radiant sits in the classic one-carat band, graded I colour (near-colourless) and SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 1428452250. Listed at 12 retailers as of November 4, 2026, with prices from HK$25,362 to HK$36,859, a HK$11,497 spread on the same certified stone. Washington Diamond lists it at HK$36,859. 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.
