About this 0.51ct natural oval diamond

This 0.51ct natural oval sits in the half to three-quarter carat band, graded J colour (near-colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6512933565. Listed at 17 retailers as of November 5, 2026, with prices from HK$3,762 to HK$12,783, a HK$9,021 spread on the same certified stone. NZ Jewellers lists it at HK$12,783. 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.
