About this 1.21ct natural marquise diamond

This 1.21ct natural marquise sits in the classic one-carat band, graded D colour (colourless) and FL clarity (flawless or internally-flawless), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 2245057220. Listed at 16 retailers as of November 1, 2026, with a 53% 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.
