About this 2.5ct natural marquise diamond

This 2.5ct natural marquise sits in the two to three carat band, graded G 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 2557186863. Listed at 2 retailers as of November 1, 2026, with prices from HK$221,092 to HK$288,309, a HK$67,217 spread on the same certified stone. Cape Diamonds lists it at HK$288,309. 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.
