About this 0.42ct natural emerald diamond

This 0.42ct natural emerald sits in the sub-half-carat band, graded I 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 5553888988. Listed at 10 retailers as of November 1, 2026, with a 145% 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.
