About this 1.8ct natural oval diamond

This 1.8ct natural oval sits in the one-and-a-half to two carat band, graded I colour (near-colourless) and I1 clarity (included), with a very-good cut grade and certified by IGI 743559055. Listed at 11 retailers as of October 30, 2026, with prices from HK$16,280 to HK$40,617, a HK$24,338 spread on the same certified stone. NZ Jewellers lists it at HK$40,617. 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.
