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 very-good cut grade stated by the retailer rather than the lab and certified by GIA 1309701203. Listed at 22 retailers as of November 2, 2026, with prices from HK$6,168 to HK$13,527, a HK$7,359 spread on the same certified stone. MOH London lists it at HK$13,527. 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.
