This 1.51ct natural marquise sits in the one-and-a-half to two carat band, graded I colour (near-colourless) and SI2 clarity (slightly-included), with a very-good cut grade and certified by IGI 837697198. Listed at 13 retailers as of October 31, 2026, with prices from HK$28,215 to HK$55,856, a HK$27,642 spread on the same certified stone. NZ Jewellers lists it at HK$55,856. 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.
