About this 1.23ct natural oval diamond

This 1.23ct 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 and certified by IGI 790682893. Listed at 16 retailers as of November 4, 2026, with prices from HK$14,797 to HK$34,265, a HK$19,468 spread on the same certified stone. NZ Jewellers lists it at HK$34,265. 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.
