About this 0.51ct natural marquise diamond

This 0.51ct natural marquise sits in the half to three-quarter carat band, graded I colour (near-colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 2566796464. Listed at 7 retailers as of November 4, 2026, with prices from HK$6,457 to HK$21,935, a HK$15,479 spread on the same certified stone. NZ Jewellers lists it at HK$21,935. 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.
