About this 1.03ct natural oval diamond

This 1.03ct natural oval sits in the classic one-carat band, graded M 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 2537093079. Listed at 10 retailers as of November 5, 2026, with prices from £457 to £1,928, a £1,471 spread on the same certified stone. NZ Jewellers lists it at £1,928. 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.
