About this 1.02ct natural radiant diamond

This 1.02ct natural radiant sits in the classic one-carat band, graded K colour (faint-tinted) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 15254481. Listed at 2 retailers as of November 6, 2026, with prices from HK$21,592 to HK$30,722, a HK$9,130 spread on the same certified stone. 77 Diamonds lists it at HK$30,722. 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.
