About this 0.3ct natural radiant diamond

This 0.3ct natural radiant sits in the sub-half-carat band, graded H colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI 815676649. Listed at 13 retailers as of October 29, 2026, with a 133% spread between the cheapest and most expensive listing. That is exactly the kind of price-discovery gap Carat Hunter was built to surface. 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.
