About this 0.5ct natural radiant diamond

This 0.5ct natural radiant sits in the half to three-quarter carat band, graded J colour (near-colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade stated by the retailer rather than the lab and certified by GIA 5546408187. Listed at a single retailer as of October 31, 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.
