About this 0.66ct natural round diamond

This 0.66ct natural round sits in the half to three-quarter carat band, graded J colour (near-colourless) and I1 clarity (included), with a standard cut grade and certified by GIA 2231822448. Listed at a single retailer as of November 2, 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.
