About this 0.9ct natural radiant diamond

This 0.9ct 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 1508605429. Listed at 11 retailers as of October 28, 2026, with prices from HK$12,318 to HK$19,672, a HK$7,355 spread on the same certified stone. Yorxs lists it at HK$19,672. 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.
