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 standard cut grade stated by the retailer rather than the lab and certified by GIA 2547783199. Listed at 26 retailers as of October 31, 2026, with prices from HK$5,657 to HK$13,343, a HK$7,685 spread on the same certified stone. MOH London lists it at HK$13,343. 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.
