About this 0.5ct natural marquise diamond

This 0.5ct natural marquise sits in the half to three-quarter carat band, graded J colour (near-colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 5556225816. Listed at 3 retailers as of October 30, 2026, with prices from HK$3,392 to HK$4,382, a HK$991 spread on the same certified stone. 77 Diamonds lists it at HK$4,382. 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.
