About this 0.5ct natural marquise diamond

This 0.5ct natural marquise sits in the half to three-quarter carat band, graded I colour (near-colourless) and SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 6561734759. Listed at 7 retailers as of November 1, 2026, with prices from HK$4,041 to HK$12,664, a HK$8,623 spread on the same certified stone. NZ Jewellers lists it at HK$12,664. 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.
