About this 1ct natural marquise diamond

This 1ct natural marquise sits in the classic one-carat band, graded I 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 1555625816. Listed at 14 retailers as of November 6, 2026, with prices from HK$19,170 to HK$49,399, a HK$30,229 spread on the same certified stone. NZ Jewellers lists it at HK$49,399. 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.
