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 VS2 clarity (very-slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 1555596509. Listed at 18 retailers as of November 4, 2026, with prices from HK$4,347 to HK$16,304, a HK$11,957 spread on the same certified stone. NZ Jewellers lists it at HK$16,304. 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.
