About this 1.4ct natural radiant diamond

This 1.4ct natural radiant sits in the one-and-a-quarter to one-and-a-half carat band, graded I colour (near-colourless) and SI1 clarity (slightly-included), with a standard cut grade and certified by IGI 239695784. Listed at 2 retailers as of October 29, 2026, with a relatively tight 5% spread, which is unusual at this carat range and suggests competitive pricing across the listings. 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.
