About this 1.15ct natural marquise diamond

This 1.15ct natural marquise sits in the classic one-carat band, graded K colour (faint-tinted) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 2175379987. Listed at 3 retailers as of November 4, 2026, with prices from HK$18,577 to HK$28,075, a HK$9,497 spread on the same certified stone. 77 Diamonds lists it at HK$28,075. 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.
