About this 0.51ct natural emerald diamond

This 0.51ct natural emerald sits in the half to three-quarter carat band, graded K colour (faint-tinted) and SI1 clarity (slightly-included) and certified by GIA 6471861378. Listed at a single retailer as of November 5, 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.
