Weight: 53.64 carats

An oval carved double-sided cabochon emerald weighing 53.64 carats, certified by GIA (Gemological Institute of America), can be considered rare and valuable
Comments: Due to their growth conditions in nature and recovery methods, most emeralds contain surface reaching features. For this reason, clarity enhancement is a common trade practice
Larger emeralds are generally rarer and more valuable, assuming all other quality factors are favorable
GIA is the most established certification company in the world. They have been around since 1931 and are the foremost authority on diamonds, gems and pearls. They are a non-profit organization that sets the standards for jewels and identification world-wide.
Gemstones are rare natural resources of nature. Each gemstone is unique. One can compare the market for gemstones well with the art market
Untreated gemstones are best suited for investment. In the case of sapphire and ruby, this implies that they are not heated, as 98...
