About this 0.54ct natural marquise diamond

This 0.54ct natural marquise sits in the half to three-quarter 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 2566376370. Listed at 3 retailers as of November 1, 2026, with prices from HK$3,919 to HK$4,788, a HK$869 spread on the same certified stone. 77 Diamonds lists it at HK$4,788. 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.
