About this 1.03ct natural radiant diamond

This 1.03ct natural radiant sits in the classic one-carat band, graded I colour (near-colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 1377931134. Listed at 11 retailers as of November 5, 2026, with prices from HK$19,162 to HK$29,445, a HK$10,283 spread on the same certified stone. Washington Diamond lists it at HK$29,445. 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.
