About this 1.3ct natural radiant diamond

This 1.3ct natural radiant sits in the one-and-a-quarter to one-and-a-half 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 3145961771. Listed at 16 retailers as of November 4, 2026, with prices from HK$27,431 to HK$61,555, a HK$34,124 spread on the same certified stone. NZ Jewellers lists it at HK$61,555. 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.
