About this 0.5ct natural oval diamond

This 0.5ct natural oval sits in the half to three-quarter carat band, graded H colour (near-colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI 754512420. Listed at 18 retailers as of November 5, 2026, with prices from £323 to £1,346, a £1,023 spread on the same certified stone. NZ Jewellers lists it at £1,346. 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.
