Natural Emeralds
Emeralds, in their natural form, are a testament to the Earth’s ability to craft beauty over millions of years. These gemstones, with their rich history and unique characteristics, have captivated humanity for centuries.
Formation Of Natural Emeralds
Natural emeralds are formed deep within the Earth’s crust, under specific conditions. They arise from the combination of beryllium (from ancient rocks), chromium, and vanadium (from younger rocks) under extreme heat and pressure. Over millions of years, these elements come together, giving birth to the emerald’s mesmerizing green hue.
Characteristics Of Natural Emeralds
Natural emeralds often contain inclusions, sometimes referred to as the stone’s “jardin” or garden. These inclusions can be seen as tiny internal or surface-reaching characteristics, adding depth and character to the gemstone. The color of natural emeralds can range from a light green to a deep, rich green, depending on the presence and concentration of chromium and vanadium.
Quality Of Natural Emeralds
The quality of a natural emerald is determined by its color, clarity, cut, and carat weight. While inclusions are common and can even add to an emerald’s uniqueness, excessive inclusions can impact its value. The most prized emeralds are those with a vivid green hue, transparent clarity, and a cut that showcases the gemstone’s brilliance.
