About this 0.8ct natural radiant diamond

This 0.8ct natural radiant sits in the just-under-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 1309121403. Listed at 3 retailers as of October 28, 2026, with prices from HK$6,553 to HK$10,403, a HK$3,850 spread on the same certified stone. 77 Diamonds lists it at HK$10,403. 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.
