About this 0.5ct natural marquise diamond

This 0.5ct natural marquise sits in the half to three-quarter carat band, graded H colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 6551995451. Listed at 19 retailers as of November 5, 2026, with prices from HK$3,911 to HK$14,679, a HK$10,769 spread on the same certified stone. NZ Jewellers lists it at HK$14,679. 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.
