About this 0.51ct natural emerald diamond

This 0.51ct natural emerald sits in the half to three-quarter carat band, graded I colour (near-colourless) and VS2 clarity (very-slightly-included), with a top-tier cut grade stated by the retailer rather than the lab and certified by GIA 6555256518. Listed at 19 retailers as of October 30, 2026, with a 241% spread between the cheapest and most expensive listing. That is exactly the kind of price-discovery gap Carat Hunter was built to surface. Compare the cross-retailer prices above before buying. The same certified stone often varies 15 to 40% across stores.
