About this 3.51ct natural marquise diamond
This 3.51ct natural marquise sits in the three to five carat band, graded H colour (near-colourless) and SI1 clarity (slightly-included) and certified by HRD 250000272767. 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.
