About this 1ct natural oval diamond

This 1ct natural oval sits in the classic one-carat band, graded K colour (faint-tinted) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 2556153700. Listed at 21 retailers as of November 1, 2026, with prices from HK$5,917 to HK$24,782, a HK$18,865 spread on the same certified stone. NZ Jewellers lists it at HK$24,782. 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.
