About this 1.64ct natural emerald diamond

This 1.64ct natural emerald sits in the one-and-a-half to two carat band, graded M colour (faint-tinted) and VS1 clarity (very-slightly-included), with a top-tier cut grade stated by the retailer rather than the lab and certified by GIA 6415942427. Listed at 9 retailers as of November 6, 2026, with a 37% 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.
