About this 0.51ct natural marquise diamond

This 0.51ct natural marquise sits in the half to three-quarter carat band, graded J colour (near-colourless) and VS1 clarity (very-slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 5566215922. Listed at 4 retailers as of November 6, 2026, with prices from HK$4,930 to HK$6,018, a HK$1,088 spread on the same certified stone. 77 Diamonds lists it at HK$6,018. 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.
