About this 0.5ct natural oval diamond

This 0.5ct natural oval sits in the half to three-quarter carat band, graded K colour (faint-tinted) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI 815656464. Listed at 15 retailers as of November 5, 2026, with prices from £376 to £1,372, a £996 spread on the same certified stone. NZ Jewellers lists it at £1,372. 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.
