About this 2.51ct natural marquise diamond

This 2.51ct natural marquise sits in the two to three 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 6545914908. Listed at 6 retailers as of November 1, 2026, with prices from HK$207,225 to HK$289,256, a HK$82,031 spread on the same certified stone. MOH London lists it at HK$289,256. 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.
