About this 1.51ct natural marquise diamond

This 1.51ct natural marquise sits in the one-and-a-half to two carat band, graded M colour (faint-tinted) and SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 6552813348. Listed at 12 retailers as of November 5, 2026, with prices from HK$18,559 to HK$43,239, a HK$24,680 spread on the same certified stone. NZ Jewellers lists it at HK$43,239. 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.
