About this 0.51ct natural oval diamond

This 0.51ct natural oval sits in the half to three-quarter carat band, graded H 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 1565302455. Listed at 16 retailers as of November 5, 2026, with prices from HK$3,010 to HK$12,798, a HK$9,789 spread on the same certified stone. NZ Jewellers lists it at HK$12,798. 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.
