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 7536520006. Listed at 12 retailers as of October 27, 2026, with prices from HK$4,276 to HK$13,048, a HK$8,772 spread on the same certified stone. NZ Jewellers lists it at HK$13,048. 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.
