This 0.51ct natural heart sits in the half to three-quarter carat band, graded K colour (faint-tinted) and VVS1 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI 815656546. Listed at 14 retailers as of November 5, 2026, with prices from HK$3,895 to HK$14,209, a HK$10,314 spread on the same certified stone. NZ Jewellers lists it at HK$14,209. 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.
