About this 0.53ct natural radiant diamond

This 0.53ct natural radiant sits in the half to three-quarter carat band, graded I colour (near-colourless) and SI2 clarity (slightly-included) and certified by GIA 5211630550. Listed at 4 retailers as of October 30, 2026, with a relatively tight 11% 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.
