About this 0.51ct natural marquise diamond

This 0.51ct natural marquise sits in the half to three-quarter carat band, graded G colour (near-colourless) and VS2 clarity (very-slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 6562665578. Listed at 15 retailers as of November 5, 2026, with prices from HK$5,173 to HK$21,772, a HK$16,600 spread on the same certified stone. NZ Jewellers lists it at HK$21,772. 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.
