About this 0.38ct natural round diamond

This 0.38ct natural round sits in the sub-half-carat band, graded J colour (near-colourless) and SI2 clarity (slightly-included), with a very-good cut grade and certified by IGI 631402761. Listed at 11 retailers as of October 28, 2026, with prices from £135 to £611, a £476 spread on the same certified stone. NZ Jewellers lists it at £611. 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.
