About this 1.5ct natural oval diamond

This 1.5ct natural oval sits in the one-and-a-half to two carat band, graded J colour (near-colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI 830647929. Listed at 14 retailers as of November 5, 2026, with prices from £2,521 to £4,947, a £2,427 spread on the same certified stone. NZ Jewellers lists it at £4,947. 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.
