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 VVS2 clarity (very-very-slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 6565419902. Listed at 18 retailers as of October 30, 2026, with prices from HK$6,614 to HK$23,231, a HK$16,617 spread on the same certified stone. NZ Jewellers lists it at HK$23,231. 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.
