About this 1.51ct natural marquise diamond

This 1.51ct natural marquise sits in the one-and-a-half to two carat band, graded D 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 5553045462. Listed at 13 retailers as of November 1, 2026, with prices from HK$56,073 to HK$90,477, a HK$34,404 spread on the same certified stone. Helzberg Diamonds lists it at HK$90,477. 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.
