About this 1.2ct natural oval diamond

This 1.2ct natural oval sits in the classic one-carat band, graded I colour (near-colourless) and IF clarity (flawless or internally-flawless), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 1479074341. Listed at 25 retailers as of November 4, 2026, with a 113% 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.
