About this 1.03ct natural radiant diamond

This 1.03ct natural radiant sits in the classic one-carat band, graded K colour (faint-tinted) and VS1 clarity (very-slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA. Listed at 2 retailers as of November 4, 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.
