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 SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 1549682009. Listed at 20 retailers as of November 5, 2026, with prices from HK$3,503 to HK$14,241, a HK$10,737 spread on the same certified stone. NZ Jewellers lists it at HK$14,241. 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.
