About this 8.17ct natural heart diamond

This 8.17ct natural heart sits in the over five carat band, graded D colour (colourless) and FL clarity (flawless or internally-flawless), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 5231965587. Listed at 12 retailers as of October 30, 2026, with a 30% 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.
