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 very-good cut grade stated by the retailer rather than the lab and certified by GIA 1559993905. Listed at 15 retailers as of November 5, 2026, with prices from HK$10,118 to HK$33,160, a HK$23,042 spread on the same certified stone. NZ Jewellers lists it at HK$33,160. 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.
