About this 1.51ct natural marquise diamond

This 1.51ct natural marquise sits in the one-and-a-half to two carat band, graded H colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 1558321176. Listed at 19 retailers as of November 5, 2026, with prices from HK$69,682 to HK$118,862, a HK$49,180 spread on the same certified stone. NZ Jewellers lists it at HK$118,862. 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.
