About this 1ct natural marquise diamond

This 1ct natural marquise sits in the classic one-carat band, graded K colour (faint-tinted) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 2556808009. Listed at 7 retailers as of November 6, 2026, with prices from HK$10,432 to HK$19,727, a HK$9,295 spread on the same certified stone. With Clarity lists it at HK$19,727. 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.
