About this 3.5ct natural marquise diamond

This 3.5ct natural marquise sits in the three to five carat band, graded F colour (colourless) and SI2 clarity (slightly-included) and certified by GIA. Listed at a single retailer as of October 27, 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.
