About this 1.21ct natural oval diamond

This 1.21ct natural oval sits in the classic one-carat band, graded J colour (near-colourless) and SI2 clarity (slightly-included), with a very-good cut grade and certified by IGI 713504316. Listed at 15 retailers as of November 5, 2026, with prices from HK$10,612 to HK$28,042, a HK$17,430 spread on the same certified stone. NZ Jewellers lists it at HK$28,042. 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.
