About this 0.91ct natural radiant diamond

This 0.91ct natural radiant sits in the just-under-one-carat band, graded E colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 2426281685. Listed at 3 retailers as of October 28, 2026, with prices from HK$17,749 to HK$27,503, a HK$9,755 spread on the same certified stone. 77 Diamonds lists it at HK$27,503. 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.
