This 1.78ct natural oval sits in the one-and-a-half to two carat band, graded M colour (faint-tinted) and SI2 clarity (slightly-included), with a very-good cut grade and certified by IGI 534245983. Listed at 9 retailers as of November 5, 2026, with prices from HK$23,081 to HK$45,284, a HK$22,203 spread on the same certified stone. NZ Jewellers lists it at HK$45,284. 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.
