This 1.58ct natural heart sits in the one-and-a-half to two carat band, graded G colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI 813629879. Listed at 12 retailers as of October 30, 2026, with prices from HK$26,708 to HK$52,883, a HK$26,175 spread on the same certified stone. NZ Jewellers lists it at HK$52,883. 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.
