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 IF clarity (flawless or internally-flawless), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6193090493. Listed at 8 retailers as of November 4, 2026, with prices from HK$140,008 to HK$225,888, a HK$85,879 spread on the same certified stone. MOH London lists it at HK$225,888. 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.
