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 very-good cut grade stated by the retailer rather than the lab and certified by GIA 2417729588. Listed at 19 retailers as of November 5, 2026, with prices from £1,121 to £3,260, a £2,140 spread on the same certified stone. NZ Jewellers lists it at £3,260. 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.
