About this 0.51ct natural oval diamond

This 0.51ct natural oval 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 7321081875. Listed at 16 retailers as of November 1, 2026, with a 99% 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.
