About this 1ct natural marquise diamond

This 1ct natural marquise sits in the classic one-carat band, graded H 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 6555405344. Listed at 14 retailers as of November 4, 2026, with prices from HK$19,531 to HK$46,147, a HK$26,616 spread on the same certified stone. NZ Jewellers lists it at HK$46,147. 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.
