About this 1.45ct natural round diamond

This 1.45ct natural round sits in the one-and-a-quarter to one-and-a-half carat band, graded K colour (faint-tinted) and I1 clarity (included), with a standard cut grade and certified by GIA 6203011681. Listed at a single retailer as of November 4, 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.
