About this 0.31ct natural radiant diamond

This 0.31ct natural radiant sits in the sub-half-carat band, graded E colour (colourless) and SI1 clarity (slightly-included) and certified by IGI 621419124. Listed at a single retailer as of October 29, 2026. If it later appears at another store, Carat Hunter will surface the price comparison automatically. 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.
