About this 0.9ct natural marquise diamond

This 0.9ct natural marquise sits in the just-under-one-carat band, graded D colour (colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 1499206668. Listed at 14 retailers as of October 31, 2026, with prices from HK$20,075 to HK$43,742, a HK$23,667 spread on the same certified stone. MOH London lists it at HK$43,742. 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.
