About this 0.91ct natural radiant diamond

This 0.91ct natural radiant sits in the just-under-one-carat band, graded F colour (colourless) and I1 clarity (included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6451620238. Listed at 8 retailers as of November 1, 2026, with prices from HK$10,344 to HK$16,518, a HK$6,174 spread on the same certified stone. Yorxs lists it at HK$16,518. 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.
