About this 2.5ct natural marquise diamond
This 2.5ct natural marquise sits in the two to three carat band, graded G colour (near-colourless) and SI1 clarity (slightly-included) and certified by GIA 6552552281. 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.
