About this 1.56ct natural round diamond

This 1.56ct natural round sits in the one-and-a-half to two carat band, graded D colour (colourless) and I1 clarity (included), with a very-good cut grade and certified by GIA 2426225860. Listed at a single retailer as of October 31, 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.
