About this 0.4ct natural oval diamond

This 0.4ct natural oval sits in the sub-half-carat band, graded I colour (near-colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI 754528433. Listed at 11 retailers as of October 28, 2026, with prices from £269 to £1,131, a £863 spread on the same certified stone. NZ Jewellers lists it at £1,131. 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.
