About this 0.5ct natural marquise diamond

This 0.5ct natural marquise sits in the half to three-quarter carat band, graded G 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 7551513494. Listed at 17 retailers as of November 2, 2026, with prices from HK$3,601 to HK$13,519, a HK$9,917 spread on the same certified stone. NZ Jewellers lists it at HK$13,519. 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.
