About this 1.3ct natural oval diamond

This 1.3ct natural oval sits in the one-and-a-quarter to one-and-a-half carat band, graded L colour (faint-tinted) and SI2 clarity (slightly-included), with a very-good cut grade and certified by IGI 788607568. Listed at 13 retailers as of November 5, 2026, with prices from £838 to £2,163, a £1,325 spread on the same certified stone. NZ Jewellers lists it at £2,163. 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.
