About this 0.66ct natural marquise diamond

This 0.66ct natural marquise sits in the half to three-quarter 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 1232939130. Listed at 3 retailers as of November 1, 2026, with prices from HK$6,970 to HK$10,642, a HK$3,672 spread on the same certified stone. MOH London lists it at HK$10,642. 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.
