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 SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 7562800704. Listed at 20 retailers as of November 7, 2026, with prices from HK$3,684 to HK$15,173, a HK$11,490 spread on the same certified stone. NZ Jewellers lists it at HK$15,173. 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.
