About this 0.51ct natural oval diamond

This 0.51ct natural oval sits in the half to three-quarter carat band, graded I colour (near-colourless) and VS2 clarity (very-slightly-included), with a very-good cut grade and certified by IGI 774683625. Listed at 15 retailers as of November 2, 2026, with prices from £327 to £1,360, a £1,033 spread on the same certified stone. NZ Jewellers lists it at £1,360. 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.
