About this 0.42ct natural marquise diamond

This 0.42ct natural marquise sits in the sub-half-carat band, graded H colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 6555539439. Listed at 21 retailers as of November 2, 2026, with prices from HK$2,887 to HK$7,972, a HK$5,084 spread on the same certified stone. MOH London lists it at HK$7,972. 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.
