About this 0.51ct natural oval diamond

This 0.51ct natural oval sits in the half to three-quarter carat band, graded G colour (near-colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6521187954. Listed at 10 retailers as of November 5, 2026, with prices from HK$4,240 to HK$15,910, a HK$11,670 spread on the same certified stone. NZ Jewellers lists it at HK$15,910. 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.
