About this 0.51ct natural oval diamond

This 0.51ct natural oval sits in the half to three-quarter carat band, graded J colour (near-colourless) and VVS1 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI 727537915. Listed at 13 retailers as of November 1, 2026, with prices from £329 to £1,366, a £1,037 spread on the same certified stone. NZ Jewellers lists it at £1,366. 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.
