About this 1ct natural oval diamond

This 1ct natural oval sits in the classic one-carat band, graded J colour (near-colourless) and VVS1 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI 617495995. Listed at 17 retailers as of November 2, 2026, with prices from £1,232 to £3,319, a £2,087 spread on the same certified stone. NZ Jewellers lists it at £3,319. 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.
