About this 2.51ct natural marquise diamond

This 2.51ct natural marquise sits in the two to three carat band, graded I colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 6565739246. Listed at 11 retailers as of November 2, 2026, with prices from HK$151,572 to HK$282,997, a HK$131,425 spread on the same certified stone. With Clarity lists it at HK$282,997. 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.
