About this 0.5ct natural round diamond

This 0.5ct natural round sits in the half to three-quarter carat band, graded K colour (faint-tinted) and IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by GIA 6531901813. Listed at 15 retailers as of November 4, 2026, with a 138% spread between the cheapest and most expensive listing. That is exactly the kind of price-discovery gap Carat Hunter was built to surface. Flawless clarity in sub-one-carat stones is rarely visible to the naked eye over VS1, so you are paying a meaningful premium for grade rather than appearance.
