This 1.09ct natural round sits in the classic one-carat band, graded K colour (faint-tinted) and IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI 778692415. Listed at 9 retailers as of October 31, 2026, with a relatively tight 21% spread, which is unusual at this carat range and suggests competitive pricing across the listings.
