About this 1.5ct natural marquise diamond

This 1.5ct natural marquise sits in the one-and-a-half to two 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 6421532753. Listed at 16 retailers as of November 1, 2026, with prices from HK$44,360 to HK$98,884, a HK$54,525 spread on the same certified stone. NZ Jewellers lists it at HK$98,884. 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.
