About this 0.54ct natural marquise diamond

This 0.54ct natural marquise sits in the half to three-quarter carat band, graded D colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 1549835888. Listed at 8 retailers as of November 1, 2026, with prices from HK$4,720 to HK$8,772, a HK$4,052 spread on the same certified stone. Ritani lists it at HK$8,772. 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.
