About this 1ct natural oval diamond

This 1ct natural oval sits in the classic one-carat band, graded L colour (faint-tinted) and I1 clarity (included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 1557304715. Listed at 7 retailers as of November 5, 2026, with prices from £611 to £1,916, a £1,305 spread on the same certified stone. NZ Jewellers lists it at £1,916. 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.
