About this 1.23ct natural radiant diamond

This 1.23ct 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 2406024276. Listed at 10 retailers as of November 2, 2026, with prices from HK$19,460 to HK$42,422, a HK$22,962 spread on the same certified stone. MOH London lists it at HK$42,422. 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.
