About this 1.51ct natural marquise diamond

This 1.51ct 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 very-good cut grade stated by the retailer rather than the lab and certified by GIA 6565816984. Listed at 9 retailers as of November 5, 2026, with prices from HK$31,694 to HK$52,192, a HK$20,497 spread on the same certified stone. Cape Diamonds lists it at HK$52,192. 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.
