About this 0.78ct natural oval diamond

This 0.78ct natural oval sits in the just-under-one-carat band, graded E colour (colourless) and SI2 clarity (slightly-included) and certified by GIA 5191485611. Listed at a single retailer as of October 28, 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.
