About this 1.51ct natural marquise diamond

This 1.51ct natural marquise sits in the one-and-a-half to two carat band, graded E colour (colourless) and SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 2556274084. Listed at 8 retailers as of October 30, 2026, with prices from HK$56,850 to HK$108,757, a HK$51,907 spread on the same certified stone. NZ Jewellers lists it at HK$108,757. 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.
