About this 1ct natural oval diamond

This 1ct natural oval sits in the classic one-carat band, graded I colour (near-colourless) and SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 1242018463. Listed at 23 retailers as of November 5, 2026, with prices from HK$16,310 to HK$41,664, a HK$25,354 spread on the same certified stone. NZ Jewellers lists it at HK$41,664. 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.
