Step into the captivating world of gemstones, where hidden secrets and fascinating discoveries await!Throughout history, colored gemstones have been regarded as valuable possessions, even predating written records. Despite their longstanding significance, the jewelry industry has not always given colored gemstones the full appreciation they deserve. The latter half of the 20th century was particularly characterized by a preference for white diamonds.
Many authors have used the term “copal” to refer to ancient and subfossil resins. The term originated from the Nahuatl language, where it was called “copalli” and was used by the Aztecs and Mayas. Over time, the term has been expanded to encompass all unfossilized resins found worldwide. Although initially associated with the resins used by the Aztecs and Mayas, copal has come to represent a broader category of unfossilized resins. According to Poinar (1992) and other researchers, copal may retain its distinctive qualities for millions of years. Therefore, attempting to define copal and amber based solely on their geological age remains problematic. Poinar (1992) suggests that the most reliable criteria for distinguishing copal from amber lie in the physical characteristics of the fossilized resin. Key factors such as solubility, hardness, and melting point provide valuable insights.
Emeralds are fascinating gemstones, known for their vibrant green color and unique inclusions. These inclusions, often called “jardin” (French for garden), give each emerald its distinctive character and natural beauty.
Pink sapphires from Vietnam’s marble-hosted mines are highly sought after for their stunning range of pink hues, including a beautiful purplish-pink shade. These gems mesmerize with their visual appeal and bring a calming effect associated with love, romance, and compassion. These gems revealed fascinating inclusion scenes, showcasing clear blue-violet color zones, intricate “dustoids,” and captivating snowflake-like inclusions forming star-like patterns. The presence of transparent crystal inclusions and varied mineral inclusions further exemplified nature’s artistry.
Gemstone enthusiasts and traders were caught off guard when the AGTA Gemological Testing Center in New York issued a warning in 2002 about the emergence of beryllium-diffused rubies and sapphires on the market. A new chapter in gemstone treatments emerged as beryllium diffusion took center stage. This innovative method carried out at high temperatures using a flux, resulted in significant visual transformations of rubies and sapphires. This treatment leads to significant changes in the color and properties of the stones, making it difficult for gemologists to identify them. A significant number of rubies and sapphires flooding the international gem markets had undergone a new treatment method involving the deliberate diffusion of Beryllium into the gemstone lattice. This revelation sparked extensive experimentation, discussions, and debates within the corundum world.
Even after 21 years, a significant volume of these treated rubies and sapphires remains in the market.

The peculiarities which distinguish this garnet from the ordinary occurrences of the species are: its variety of shades and tints, for the most part similar to those belonging to the rhododendrons and roses; its surprisingly small amount of coloring matter; its gem-like transparency; its freedom of internal imperfections, microscopic inclusions and striae, all so universally characteristic of common garnets; also, its remarkable brilliancy when cut as a gem
