This 1.51ct natural heart sits in the one-and-a-half to two carat band, graded K colour (faint-tinted) and VS2 clarity (very-slightly-included), with a very-good cut grade and certified by IGI 737518410. Listed at 9 retailers as of November 3, 2026, with prices from HK$18,449 to HK$40,606, a HK$22,156 spread on the same certified stone. NZ Jewellers lists it at HK$40,606. 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.
