About this 1.2ct natural oval diamond

This 1.2ct natural oval sits in the classic one-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 5513406278. Listed at 23 retailers as of October 30, 2026, with prices from HK$22,415 to HK$48,557, a HK$26,142 spread on the same certified stone. NZ Jewellers lists it at HK$48,557. 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.
