This 0.51ct natural marquise sits in the half to three-quarter carat band, graded K colour (faint-tinted) and VS1 clarity (very-slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6562380366. Listed at 2 retailers as of November 1, 2026, with prices from HK$4,276 to HK$5,118, a HK$842 spread on the same certified stone. 77 Diamonds lists it at HK$5,118. 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.
