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 very-good cut grade stated by the retailer rather than the lab and certified by GIA 6532423927. Listed at 5 retailers as of November 4, 2026, with prices from HK$5,314 to HK$9,874, a HK$4,560 spread on the same certified stone. MOH London lists it at HK$9,874. 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.
