About this 1ct natural marquise diamond

This 1ct natural marquise sits in the classic one-carat band, graded E colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 2568421607. Listed at 19 retailers as of November 5, 2026, with prices from HK$18,075 to HK$41,752, a HK$23,677 spread on the same certified stone. NZ Jewellers lists it at HK$41,752. 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.
