This 0.51ct natural marquise sits in the half to three-quarter carat band, graded K colour (faint-tinted) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI 741551063. Listed at 13 retailers as of November 1, 2026, with prices from HK$2,978 to HK$15,142, a HK$12,164 spread on the same certified stone. NZ Jewellers lists it at HK$15,142. 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.
