About this 0.9ct natural round diamond

This 0.9ct natural round sits in the just-under-one-carat band, graded E colour (colourless) and FL clarity (flawless or internally-flawless), with a top-tier cut grade and certified by GIA 6452005898. Listed at a single retailer as of October 29, 2026. If it later appears at another store, Carat Hunter will surface the price comparison automatically. 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.
