About this 0.9ct natural round diamond

This 0.9ct natural round sits in the just-under-one-carat band, graded K colour (faint-tinted) and SI1 clarity (slightly-included), with a very-good cut grade and certified by GIA 6442667694. Listed at 17 retailers as of November 4, 2026, with prices from HK$10,465 to HK$31,396, a HK$20,931 spread on the same certified stone. NZ Jewellers lists it at HK$31,396. 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.
