About this 0.5ct natural marquise diamond

This 0.5ct natural marquise sits in the half to three-quarter carat band, graded G colour (near-colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 2568439850. Listed at 17 retailers as of November 5, 2026, with prices from HK$3,958 to HK$16,568, a HK$12,610 spread on the same certified stone. NZ Jewellers lists it at HK$16,568. 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.
