About this 3.68ct natural marquise diamond

This 3.68ct natural marquise sits in the three to five carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless) and certified by GIA 2131671989. Listed at 2 retailers as of October 31, 2026, with a relatively tight 11% spread, which is unusual at this carat range and suggests competitive pricing across the listings. 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.
