About this 1ct natural oval diamond

This 1ct natural oval sits in the classic one-carat band, graded K colour (faint-tinted) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI 499121747. Listed at 14 retailers as of November 5, 2026, with prices from £1,333 to £3,600, a £2,267 spread on the same certified stone. NZ Jewellers lists it at £3,600. 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.
