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 SI2 clarity (slightly-included), with a very-good cut grade and certified by IGI 800673931. Listed at 11 retailers as of October 30, 2026, with prices from HK$2,880 to HK$11,981, a HK$9,101 spread on the same certified stone. NZ Jewellers lists it at HK$11,981. 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.
