About this 0.78ct natural oval diamond

This 0.78ct natural oval sits in the just-under-one-carat band, graded J colour (near-colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI 728566020. Listed at 18 retailers as of October 30, 2026, with prices from £638 to £2,199, a £1,560 spread on the same certified stone. NZ Jewellers lists it at £2,199. 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.
