About this 0.8ct natural marquise diamond

This 0.8ct natural marquise sits in the just-under-one-carat band, graded E colour (colourless) and SI1 clarity (slightly-included) and certified by GIA 6565009096. Listed at 14 retailers as of October 26, 2026, with a 129% spread between the cheapest and most expensive listing. That is exactly the kind of price-discovery gap Carat Hunter was built to surface. 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.
