About this 0.51ct natural oval diamond

This 0.51ct natural oval sits in the half to three-quarter 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 5506016811. Listed at 5 retailers as of November 2, 2026, with prices from HK$4,373 to HK$8,202, a HK$3,828 spread on the same certified stone. MOH London lists it at HK$8,202. 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.
