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 very-good cut grade stated by the retailer rather than the lab and certified by GIA 1275456707. Listed at 10 retailers as of November 1, 2026, with prices from HK$18,488 to HK$39,177, a HK$20,689 spread on the same certified stone. MOH London lists it at HK$39,177. 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.
