About this 0.75ct natural heart diamond

This 0.75ct natural heart sits in the just-under-one-carat band, graded E colour (colourless) and SI1 clarity (slightly-included) and certified by GIA 7383586340. Listed at 7 retailers as of November 3, 2026, with a 26% 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.
